The HCF of 2472, 1284, and a third number N is 12.
If their LCM is 2³ × 3² × 5 × 103 × 107, then which of the following could be the value of N?
- A2² × 3² × 7
- B2² × 3³ × 103
- C2² × 3² × 5
- D3³ × 103
- E2² × 3²
Show answerHide answer
Answer: C ✓ official key
Approach: HCF takes the lowest power of each common prime; LCM takes the highest power of every prime.
Solution:
2472 = 2³ × 3 × 103 and 1284 = 2² × 3 × 107.
HCF of all three = 12 = 2² × 3 → N must be divisible by 2² × 3, and N's power of 2 is at most 3.
LCM = 2³ × 3² × 5 × 103 × 107. The two given numbers supply 2³, 103, 107 but only 3¹ and no 5.
So N must supply 3² (exactly, not 3³) and 5¹, and must not bring any new prime.
Minimum such N = 2² × 3² × 5 = 180 → matches option C.
Why the other options are wrong:
- A: contains 7 and no 5 → LCM would have 7 and lack 5.
- B: 3³ makes LCM contain 3³, and 5 is missing.
- D: no factor 2² → HCF would become 3, not 12; also 3³ and no 5.
- E: no 5 → LCM would lack 5.
Cetking shortcut: Look only for the prime missing from the two given numbers (here 5) plus the exact power 3² — only C has both.
Answer: C
The smallest perfect square number that is exactly divisible by 2, 3, 4, 6, 9, 18, 30, and 60 is k², where k is a natural number.What is the sum of all prime factors of k?
- A8
- B9
- C10
- D11
- E12
Show answerHide answer
Answer: C ✓ official key
Approach: Least perfect square divisible by a set = LCM of the set made to have all even exponents.
Solution:
LCM(2, 3, 4, 6, 9, 18, 30, 60) = 2² × 3² × 5 = 180.
Exponent of 5 is odd → multiply by 5: 180 × 5 = 900 = 30².
k = 30 = 2 × 3 × 5.
Sum of prime factors of k = 2 + 3 + 5 = 10.
Cetking shortcut: Primes appearing anywhere in the list are 2, 3, 5 — k must contain each, so the sum is 10 directly.

Show answerHide answer
Answer: B ✓ official key
Approach: Remainder of a sum = remainder of the sum of individual remainders.
Solution:
Sum = 73 + 75 + 78 + 57 + 197 = 480.
34 × 14 = 476.
480 − 476 = 4.
Cetking shortcut: Remainders by 34: 5 + 7 + 10 + 23 + 27 = 72 → 72 − 68 = 4.
Answer: B
In a sanctuary, there are horses and ostriches. Each animal has one head. The total number of heads is 86 and the total number of legs is 250. How many ostriches are there?
- A45
- B46
- C47
- D48
- E49
Show answerHide answer
Answer: C ✓ official key
Approach: Heads–legs problem: two linear equations in two unknowns.
Solution:
Let horses = h, ostriches = o.
Heads: h + o = 86. Legs: 4h + 2o = 250.
Halve legs: 2h + o = 125 → subtract heads equation: h = 39.
o = 86 − 39 = 47.
Cetking shortcut: If all 86 were ostriches → 172 legs; extra 250 − 172 = 78 legs ÷ 2 per horse = 39 horses → ostriches = 47.
Answer: C
There are two examination halls, X and Y.
Statement I:
If 15 students are shifted from hall X to hall Y, then the number of students in both halls, becomes equal.
Statement II:
If 25 students are shifted from hall Y to hall X, then the number of students in hall X becomes twice the number of students in hall Y.
Based on the above statements, answer the following question:
The number of students in halls, X and Y, respectively, is:
- A90, 60
- B105, 75
- C120, 90
- D135, 105
- E140, 60
Show answerHide answer
Answer: D ✓ official key
Approach: Translate each transfer statement into a linear equation and solve.
Solution:
Let hall X = x, hall Y = y.
I: x − 15 = y + 15 → x − y = 30.
II: x + 25 = 2(y − 25) → x = 2y − 75.
Substitute: 2y − 75 − y = 30 → y = 105, x = 135.
Check: 135+25 = 160 = 2 × 80 = 2 × (105−25). ✓
Cetking shortcut: Only options with x − y = 30 survive (A, B, C, D); test II on them — only 135, 105 gives 160 = 2 × 80.
Answer: D
The sum of three numbers in a GP is 26 and their product is 216. What are the three numbers?
- A16, 6, 4
- B4, 6, 16
- C9, 6, 11
- D2, 6, 18
- E5, 7, 14
Show answerHide answer
Answer: D ✓ official key
Approach: Three numbers in GP: take them as a/r, a, ar so the product is a³.
Solution:
Product a³ = 216 → a = 6.
Sum: 6/r + 6 + 6r = 26 → 6/r + 6r = 20 → 3r² − 10r + 3 = 0.
r = 3 or 1/3 → numbers 2, 6, 18.
Check: 2 + 6 + 18 = 26, 2 × 6 × 18 = 216. ✓
Why the other options are wrong:
- A, B: 4, 6, 16 sums to 26 but 6/4 ≠ 16/6 (not a GP); product 384.
- C: 9, 6, 11 is not a GP; product 594.
- E: 5, 7, 14 is not a GP; product 490.
Cetking shortcut: Middle term of a 3-term GP = cube root of the product = 6; then check which option has 6² = first × third (2 × 18 = 36).

Approach: Difference series — differences are consecutive perfect squares.
Solution:
Differences: 650→601 = −49, 601→565 = −36, 565→540 = −25, 540→524 = −16.
These are −7², −6², −5², −4² → next is −3² = −9.
524 − 9 = 515.

Show answerHide answer
Answer: C ✓ official key
Approach: Second-difference series — the differences grow by a constant 16.
Solution:
Known differences: 118 − 94 = 24, 158 − 118 = 40 (+16).
Next differences: 56, 72, 88.
Missing term = 158 + 56 = 214.
Check: 214 + 72 = 286, 286 + 88 = 374. ✓
Cetking shortcut: Use the end: 374 − 286 = 88, so the difference before is 72 → 286 − 72 = 214.

Find the value of (1 − 1/3)(1 − 1/4)(1 − 1/5)...(1 − 1/100)
- A99/100
- B2/100
- C1
- D101/100
- E101/100
Show answerHide answer
Answer: B ✓ official key
Approach: Telescoping product: (1 − 1/n) = (n − 1)/n.
Solution:
Product = (2/3)(3/4)(4/5)…(99/100).
Every numerator cancels the previous denominator.
Only the first numerator (2) and last denominator (100) remain → 2/100 (= 1/50).
Why the other options are wrong:
- A: 99/100 is just the last factor.
- C: the product of fractions less than 1 cannot be 1.
- D, E: 101/100 is greater than 1 — impossible for a product of proper fractions (D and E are identical in the paper).
Cetking shortcut: First numerator over last denominator.
Answer: B
If
x + 1/x = 2,
then the value of
(2x² + 2)/(3x² + 5x + 3)
is:
- A4/11
- B1/2
- C1 (3/4)
- D2 (1/3)
- E1
Show answerHide answer
Answer: A ✓ official key
Approach: x + 1/x = 2 forces x = 1 (for real x).
Solution:
x + 1/x = 2 → x² − 2x + 1 = 0 → (x − 1)² = 0 → x = 1.
(2x² + 2)/(3x² + 5x + 3) = (2 + 2)/(3 + 5 + 3) = 4/11.
Cetking shortcut: Divide numerator and denominator by x: 2(x + 1/x) / (3(x + 1/x) + 5) = 4/(6 + 5) = 4/11.

- D37.304
- E38.304
Show answerHide answer
Answer: D ✓ official key
Approach: Shift the decimal in pairs: √(13 × 100ⁿ) and √(130 × 100ⁿ) only move the decimal point.
Solution:
√1.3 = √(130/100) = √130 / 10 = 11.40 / 10 = 1.140.
√1300 = √(13 × 100) = 10√13 = 36.05.
√0.013 = √(130/10000) = √130 / 100 = 0.114.
Sum = 1.140 + 36.05 + 0.114 = 37.304.
Cetking shortcut: Count digits in pairs from the decimal point: 1.3 → 130 family, 1300 → 13 family, 0.013 → 130 family. No √10 needed.

Answer: A ✓ official key
Approach: List the primes, drop the end values, then average.
Solution:
First ten odd primes: 3, 5, 7, 11, 13, 17, 19, 23, 29, 31.
Exclude smallest 3 and largest 31.
Sum of remaining 8 = 5 + 7 + 11 + 13 + 17 + 19 + 23 + 29 = 124.
Average = 124 / 8 = 15.5.
Cetking shortcut: Total of all ten = 158; 158 − 34 = 124; 124/8 = 15.5.

Show answerHide answer
Answer: A ✓ official key
Approach: Weighted average / alligation of two groups.
Solution:
Let total workers = n.
9000n = 15 × 5000 + (n − 15) × 10000.
9000n = 75000 + 10000n − 150000 → 1000n = 75000 → n = 75.
Cetking shortcut: Alligation: officers are 4000 below average, others 1000 above → officers : others = 1 : 4 → 15 : 60 → total 75.

Show answerHide answer
Answer: A ✓ official key
Approach: Chain the ratios by making the common term equal.
Solution:
A : B = 3 : 4 = 6 : 8 and B : C = 8 : 10 → A : B : C = 6 : 8 : 10.
C : D = 15 : 17; make C = 30 (LCM of 10 and 15): A : B : C = 18 : 24 : 30 and C : D = 30 : 34.
A : B : C : D = 18 : 24 : 30 : 34, total 106 parts.
1 part = 212 / 106 = 2 → D = 34 × 2 = 68.
Cetking shortcut: 212 = 2 × 106, so the answer must be 2 × (D's parts); only 68 = 2 × 34 fits once C is scaled to 30.

Show answerHide answer
Answer: B ✓ official key
Approach: Write the final quantities as ratio multiples k, then add back what was removed.
Solution:
After changes: Aman = 46k, Rohit = 41k, Suresh = 34k.
Original: Aman = 46k + 30, Rohit = 41k + 30, Suresh = 34k + 25.
Total: 121k + 85 = 2505 → 121k = 2420 → k = 20.
Rohit received 41 × 20 + 30 = 850.
Cetking shortcut: 2505 − 85 = 2420 is divisible by 121 (= 46 + 41 + 34) → k = 20 at once.

- D35
- E40
Show answerHide answer
Official CET key: C · Cetking's answer: E — see why below
Approach: Convert every average into a total at a fixed time point, then shift ages carefully.
Solution:
5 years ago: P + Q = 2 × 15 = 30 → now P + Q = 40.
5 years from now: (P + Q + 10) + (R + 5) = 3 × 25 = 75.
50 + R + 5 = 75 → R = 20 (present age).
Check with R = Q − 5: Q = 25, P = 15 → consistent.
R after 10 years = 20 + 10 = 30.
Why the other options are wrong:
- E (40): does not satisfy the totals; R is 20 now, so 30 after 10 years.
- A (20): R's present age, not after 10 years.
- B, D: do not satisfy the totals.
Cetking shortcut: Total of P, Q at +5 years = 30 + 2 × 10 = 50; three-person total 75 → R at +5 = 25 → R at +10 = 30.

- A25%
- B30%
- C28%
- D32%
- E35%
Show answerHide answer
Answer: B ✓ official key
Approach: Overall pass % = total passed / total students (weighted, not simple average).
Solution:
Total students = 20 + 40 + 60 + 80 = 200.
Passed = 10% of 20 + 20% of 40 + 30% of 60 + 40% of 80 = 2 + 8 + 18 + 32 = 60.
Pass % = 60/200 × 100 = 30%.
Cetking shortcut: Weights 1 : 2 : 3 : 4 → (10 + 40 + 90 + 160)/10 = 30%.

- C₹2,35,230
- D₹2,30,400
- E₹2,60,000
Show answerHide answer
Answer: C ✓ official key
Approach: Depreciation: Value = P(1 − r/100)ⁿ.
Solution:
Value = 3,20,000 × (0.95)⁶.
(0.95)² = 0.9025; (0.95)³ = 0.857375; (0.95)⁶ = 0.857375² ≈ 0.73509.
Value ≈ 3,20,000 × 0.73509 ≈ ₹2,35,229 ≈ ₹2,35,230.
Cetking shortcut: Binomial: (1 − 0.05)⁶ ≈ 1 − 0.30 + 0.0375 − 0.0025 ≈ 0.735 → 3,20,000 × 0.735 ≈ 2,35,200 → C.

The price of raw materials has increased by 15%. Labour cost has also increased from 25% of the cost of raw material to 30% of the cost of raw material. By how much percentage should the usage of raw materials be reduced so as to keep the total cost the same?
- A15.2 %
- B16.4 %
- C18.6 %
- D19.8 %
- E20 %
Show answerHide answer
Answer: B ✓ official key
Approach: Fix the old total cost; let usage of raw material become a fraction u and keep total cost equal.
Solution:
Old: raw material cost = 100, labour = 25% of 100 = 25, total = 125.
New price of raw material = 115 per old unit of usage; labour = 30% of raw material cost.
New total = 115u + 0.30 × 115u = 149.5u.
149.5u = 125 → u = 0.8361.
Reduction in usage = (1 − 0.8361) × 100 ≈ 16.4%.
Cetking shortcut: Reduction = 1 − 125/149.5 = 24.5/149.5 ≈ 16.4%.

- B72 km/h
- C90 km/h
- D25 m/s
- E30 m/s
Show answerHide answer
Answer: C ✓ official key
Approach: Crossing a pole: distance = length of the train.
Solution:
Speed = 200 m / 8 s = 25 m/s.
In km/h: 25 × 18/5 = 90 km/h.
Why the other options are wrong:
- A, B: wrong conversions (18 and 72 km/h = 5 and 20 m/s).
- D: 25 m/s is numerically the same speed as 90 km/h; the official key takes the km/h form.
- E: 30 m/s = 108 km/h.
Cetking shortcut: m/s → km/h: multiply by 3.6.

- C28 km/h
- D30 km/h
- E32 km/h
Show answerHide answer
Answer: D ✓ official key
Approach: Average speed = total distance / total time (not the mean of speeds).
Solution:
Take total distance = 6 units (LCM of 2 and 3): parts 3, 2, 1.
Time = 3/30 + 2/40 + 1/20 = 0.1 + 0.05 + 0.05 = 0.2.
Average speed = 6 / 0.2 = 30 km/h.
Cetking shortcut: Better: take distance = 120 km → 60/30 + 40/40 + 20/20 = 2 + 1 + 1 = 4 h → 120/4 = 30.

Two pipes A and B can fill a tank in 24 minutes and 32 minutes respectively. If both the pipes are opened simultaneously, after how much time should B be closed so that the tank is full in 18 minutes?
- A8 minutes
- B9 minutes
- C7 minutes
- D15 minutes
- E24 minutes
Show answerHide answer
Answer: A ✓ official key
Approach: Work done by each pipe = rate × time it stays open.
Solution:
A works all 18 min: 18/24 = 3/4 of the tank.
B must fill the remaining 1/4: x/32 = 1/4 → x = 8 min.
B should be closed after 8 minutes.
Cetking shortcut: Remaining fraction × B's time = 1/4 × 32 = 8.
Answer: A
A cistern is normally filled in 6 hours but takes 4 hours longer to fill because of a leak in its bottom. If the cistern is full, the leak will empty it in how much time?
- A15 hours
- B16 hours
- C12 hours
- D20 hours
- E24 hours
Show answerHide answer
Answer: A ✓ official key
Approach: Leak rate = filling rate without leak − net rate with leak.
Solution:
Pipe alone: 1/6 per hour; with leak the tank takes 10 h → 1/10 per hour.
Leak rate = 1/6 − 1/10 = (5 − 3)/30 = 1/15.
The leak empties a full tank in 15 hours.
Cetking shortcut: Leak time = (6 × 10)/(10 − 6) = 60/4 = 15 h.

Approach: Rates in AP: first = x, second = x + d, third = x + 2d; use the 10-day/14-day equality.
Solution:
10(x + 2d) = 14x → 20d = 4x → x = 5d.
Rates: 5d, 6d, 7d → together 18d per day (one shift per day).
6 days: 6 × 18d = 108d = 324 → d = 3.
First digger = 5d = 15 m per shift.
Why the other options are wrong:
- B (18 m): second digger's rate (6d).
- C (21 m): third digger's rate (7d).
- D, E: do not satisfy 10 × third = 14 × first.
Cetking shortcut: Third : first = 14 : 10 = 7 : 5 → rates 5 : 6 : 7; daily total 324/6 = 54 = 18 parts → 1 part = 3 → first = 15.

If the speed of a boat in still water is 8 km/h and the rate of stream is 4 km/h, what is the upstream speed of the boat?
- A12 km/h
- B8 km/h
- C6 km/h
- D4 km/h
- E3 km/h
Show answerHide answer
Answer: D ✓ official key
Approach: Upstream speed = boat speed − stream speed.
Solution:
Upstream = 8 − 4 = 4 km/h.
Why the other options are wrong:
- A: 12 km/h is the downstream speed (8 + 4).
Answer: D
In a 24-hour period, the hour and minute hands of a clock are at right angles to each other excluding all positions where the hands overlap or are directly opposite. How many such right-angle positions occur?
- A40
- B42
- C44
- D46
- E48
Show answerHide answer
Answer: C ✓ official key
Approach: In 12 hours the hands are at right angles 22 times (not 24); double it for a day.
Solution:
In 12 hours the minute hand gains 11 full rounds on the hour hand.
Each round produces 2 right angles → 22 right angles in 12 hours.
In 24 hours: 22 × 2 = 44.
Overlaps and straight-line positions are separate events and are not counted anyway.
Why the other options are wrong:
- E (48): assumes 2 per hour × 24 — ignores that the hands gain only 22 rounds in a day.
- A, B, D: miscounts.
Cetking shortcut: Right angles = 44, straight (opposite) = 22, coincide = 22 in a day — memorise this triplet.

Answer: C ✓ official key
Approach: Count odd days from 26 January to 14 November (2026 is not a leap year).
Solution:
Odd days after 26 Jan: Jan 5, Feb 0, Mar 3, Apr 2, May 3, Jun 2, Jul 3, Aug 3, Sep 2, Oct 3, Nov 14 → 0.
Total = 5 + 0 + 3 + 2 + 3 + 2 + 3 + 3 + 2 + 3 + 0 = 26 → 26 mod 7 = 5.
(Check: 292 days = 41 weeks + 5 days.)
Monday + 5 = Saturday.
Cetking shortcut: Month codes: 26 Jan Monday → 14 Nov is 292 days later; 292 = 287 + 5 → Monday + 5 = Saturday.

A bag contains 5 red and 7 green balls. Two balls are drawn one after the other, with replacement of the first ball before drawing the second. What is the probability that both balls drawn are red?
- A5/12
- B25/144
- C5/24
- D35/144
- E1/2
Show answerHide answer
Answer: B ✓ official key
Approach: With replacement the draws are independent: multiply probabilities.
Solution:
P(red) = 5/12 on each draw.
P(both red) = 5/12 × 5/12 = 25/144.
Why the other options are wrong:
- A: probability of a single red.
- C, D: mix of without-replacement / red-green products (35/144 = one red and one green in a fixed order).
Answer: B

The volume V of a pyramid varies jointly as its height h and the area of its base .A pyramid has a base area of 48 dm² and a height of 150 cm, giving a volume of 240 dm³.Find the area of the base (in cm²) of another pyramid whose volume is 420 dm³ and whose height is 180 cm.
- A4200 cm²
- B7000 cm²
- C7200 cm²
- D8400 cm²
- E5600 cm²
Show answerHide answer
Answer: B ✓ official key
Approach: Joint variation: V = kAh. Keep all units in dm.
Solution:
150 cm = 15 dm, 180 cm = 18 dm.
240 = k × 48 × 15 → k = 240/720 = 1/3.
420 = (1/3) × A × 18 → A = 420/6 = 70 dm².
70 dm² = 70 × 100 cm² = 7000 cm².
Cetking shortcut: A₂ = A₁ × (V₂/V₁) × (h₁/h₂) = 48 × 7/4 × 5/6 = 70 dm²; 1 dm² = 100 cm².
Answer: B
A tank measures 99 cm × 120 cm × 80 cm. It is to be filled using a cylindrical bucket of radius 12 cm and height 20 cm. If the bucket is filled up to 75% of its height each time, what is the minimum number of times the bucket must be used to completely fill the tank?
- A120
- B130
- C140
- D135
- E145
Show answerHide answer
Answer: C ✓ official key
Approach: Number of fills = tank volume / volume carried per fill (π = 22/7).
Solution:
Tank = 99 × 120 × 80 = 9,50,400 cm³.
Water per fill = π × 12² × (75% of 20 = 15) = (22/7) × 144 × 15 = 47520/7 cm³.
Fills = 950400 × 7 / 47520 = 140.
Cetking shortcut: 99 = 9 × 11 and 7 pairs with 22/7 — the numbers are built to cancel; 950400 ÷ 6788.57 = 140 exactly with π = 22/7.

Approach: Curved surface area of a cone = πrl.
Solution:
Equal diameters → equal r.
CSA₁ : CSA₂ = πrl₁ : πrl₂ = l₁ : l₂ = 5 : 7.
Why the other options are wrong:
- B: squares the ratio (that would be for similar figures' areas).
- A, C, E: no basis.

Approach: Find the rule linking the two numbers of each pair: second = 3 × first + 1.
Solution:
15 → 46 (45 + 1), 12 → 37 (36 + 1), 9 → 28 (27 + 1), 20 → 61 (60 + 1).
8 → 3 × 8 + 1 = 25, but the pair shows 33 → odd one out.
Why the other options are wrong:

Approach: Compare each number with the nearby perfect cube.
Solution:
25 = 3³ − 2, 62 = 4³ − 2, 123 = 5³ − 2, 341 = 7³ − 2.
218 = 6³ + 2 → the only one with +2 → odd one out.
Why the other options are wrong:

Approach: Women together → treat them as one block.
Solution:
Units: 5 men + 1 women-block = 6 → 6! = 720 ways.
Women inside the block: 4! = 24 ways.
Total = 720 × 24 = 17,280.
Why the other options are wrong:
- A: forgets the internal 4! arrangement.
- B, C: partial counts (e.g. 6! × 3!, 6! × 4!/2).
- E: double-counts (×2).

How many words can be formed out of the letters of the word 'EDUCATION' such that vowels occupy the odd positions?
- A1440
- B2880
- C2840
- D2480
- E720
Show answerHide answer
Answer: B ✓ official key
Approach: Place vowels in their allowed positions, then consonants in the rest.
Solution:
EDUCATION: 9 distinct letters — vowels E, U, A, I, O (5), consonants D, C, T, N (4).
Odd positions 1, 3, 5, 7, 9 = 5 places → vowels: 5! = 120.
Remaining 4 even places → consonants: 4! = 24.
Total = 120 × 24 = 2880.
Why the other options are wrong:
- A: halves the answer (counts only one group fully).
- E: only 5! × 3! style partial count.
- C, D: arithmetic misreads of 2880.
Cetking shortcut: 5 vowels exactly fill 5 odd slots → answer is simply 5! × 4!.

Study the Pie Chart and answer the question that follow.
The pie chart represents the distribution of the annual agricultural yield of a certain place among different crops in terms of their central angles.
Data read from chart:
| Crop | Central angle |
|---|
| Rice | 108° |
| Wheat | 90° |
| Maize | 54° |
| Pulses | 36° |
| Sugarcane | 72° |
If the total annual agricultural production is 4800 tonnes, what is the difference between the production of Rice and Wheat?
- A120 tonnes
- B180 tonnes
- C240 tonnes
- D300 tonnes
- E360 tonnes
Show answerHide answer
Answer: C ✓ official key
Approach: Value = (central angle / 360°) × total.
Solution:
Rice − Wheat = 108° − 90° = 18°.
18/360 × 4800 = 4800/20 = 240 tonnes.
Cetking shortcut: Work with the angle difference directly: 1° = 4800/360 = 13.33 t → 18° = 240 t.
Answer: C
Refer to the passage above ↑
If the production of Sugarcane is increased by 20%, what will be its new percentage share (approx.) in total production, assuming others remain constant?
- A20%
- B23%
- C25%
- D28 %
- E40 %
Show answerHide answer
Answer: B ✓ official key
Approach: Increase one sector and recompute its share over the NEW total.
Solution:
Sugarcane = 72/360 = 20% of total (take total = 100).
After 20% increase: 20 × 1.2 = 24; new total = 100 + 4 = 104.
New share = 24/104 × 100 ≈ 23.08% ≈ 23%.
Why the other options are wrong:
- A: ignores the increase.
- C: uses a 25% increase and/or forgets the total grows.
- D, E: overstated shares.
Cetking shortcut: If a part p% grows by r%, new share = p(1 + r)/(100 + pr) → 24/104.
Answer: B
Refer to the passage above ↑
If Rice production decreases by 10% and Wheat production increases by 10%, which crop will have the highest production?
- ARice
- BWheat
- CSugarcane
- DMaize
- EPulses
Show answerHide answer
Answer: B ✓ official key
Approach: Apply the changes to the sector angles and compare.
Solution:
Rice: 108 × 0.9 = 97.2°.
Wheat: 90 × 1.1 = 99°.
Others unchanged: Sugarcane 72°, Maize 54°, Pulses 36°.
Wheat (99°) is now the highest.
Why the other options are wrong:
- A: Rice drops to 97.2°, below Wheat.
- C, D, E: 72°, 54°, 36° are far below.
Answer: B
Refer to the passage above ↑
The production of Rice, Wheat, and Sugarcane together exceeds the production of Maize and Pulses by what ratio?
- A2 : 1
- B3 : 1
- C4 : 1
- D5 : 2
- E7 : 3
Show answerHide answer
Answer: B ✓ official key
Approach: Compare the summed angles of the two groups.
Solution:
Rice + Wheat + Sugarcane = 108 + 90 + 72 = 270°.
Maize + Pulses = 54 + 36 = 90°.
Ratio = 270 : 90 = 3 : 1.
Why the other options are wrong:
- A (2 : 1): ratio of the excess (270 − 90 = 180) to 90 — the question asks for the ratio of the two totals.
- C, D, E: do not match 270 : 90.
Cetking shortcut: The two groups make the whole 360°: 90° vs 270° → 1 : 3 instantly.
Answer: B
Refer to the passage above ↑
If the production of Pulses is decreased by 20% and the production of Sugarcane is increased by 20%, while the total production remains unchanged, which of the following will be true?
- APulses will have the lowest production
- BSugarcane will have higher production than Wheat
- CSugarcane will have equal production as Rice
- DPulses will have higher production than Maize
- ERice will lose its top position
Show answerHide answer
Answer: A ✓ official key
Approach: Apply the changes to the angles and test each statement.
Solution:
Pulses: 36 × 0.8 = 28.8°. Sugarcane: 72 × 1.2 = 86.4°.
Others: Rice 108°, Wheat 90°, Maize 54°.
Pulses (28.8°) is still the lowest → A is true.
Why the other options are wrong:
- B: Sugarcane 86.4° < Wheat 90°.
- C: 86.4° ≠ Rice 108°.
- D: Pulses 28.8° < Maize 54°.
- E: Rice 108° remains on top.
Cetking shortcut: Pulses was already the smallest and it only falls — A is true without calculating.

- A₹20 lakhs
- B₹30 lakhs
- C₹ 5 lakhs
- D₹10 lakhs
- E₹ 25 lakhs
Show answerHide answer
Official CET key: C · Cetking's answer: B — see why below
Approach: Filter the years by the condition, then add Overhead for those years.
Solution:
Training − Promotion: 2021: 5 − 10 = −5; 2022: 10 − 15 = −5; 2023: 15 − 5 = 10; 2024: 5 − 5 = 0; 2025: 10 − 10 = 0.
Only 2023 satisfies 'at least ₹10 lakh'.
Overhead in 2023 = 50 − 45 = ₹5 lakh.
Why the other options are wrong:
- A, B, E: add Overhead of years that fail the condition (e.g. all five years = 30).
- D: misreads the 2023 Overhead segment as 10 (or adds 2025's 10).
Cetking shortcut: Only one bar (2023) has a tall Training and a thin Promotion segment — read just that bar.

Which of the following follows from the passage above?
- AA rhetoric laden talk can generate authentic democratic collective choice.
- BIrrational persons alone can have values.
- CAuthenticity of democracy requires a strong reflection-action interaction.
- DA paradigm of competition alone can sustain an authentic democracy.
- Edemocracy requires a weak reflection-action interaction.
Show answerHide answer
Answer: C ✓ official key
Approach: Inference — paraphrase the second sentence of the passage.
Solution: Line 2: "The authenticity of democracy requires in addition that these reflective preferences influence collective outcomes and action." Reflection (reordering of preferences) must flow into action (collective outcomes). That is a strong reflection–action interaction — exactly option C.
Why the other options are wrong:
A: Rhetoric-laden talk is called strategic, "deceptive and coercive" — a threat to authenticity, not its source.
B: The passage says values may be realised only when individuals behave non-rationally; it never says only irrational persons have values.
D: Competition is an unstated theme that introduces strategy; 'alone can sustain' is unsupported and extreme.
E: Direct opposite of C — reflection must influence action, so the link is strong, not weak.
Cetking shortcut: When two options are exact opposites (C vs E), one of them is usually the answer — check which one the text supports.
Answer: C
Refer to the passage above ↑
Desire as ante-deliberation driving action refer to
- AIrrationality of deliberation.
- BUselessness of deliberation.
- CDesire to act without thinking.
- DTemporal inconsistency in a position that argues for deliberative action constituting democracy.
- EThoughtlessness of deliberation.
Show answerHide answer
Answer: D ✓ official key
Approach: Inference — decode 'ante' (= before) and see what it does to the deliberative-democracy argument.
Solution: Para 2: "Most human actions and discourses are actuated by a deeper or primordial ante-deliberation Desire… Engaging in a deliberation or else in an action is possible only since there has been such a Desire." So something non-deliberative comes before every deliberation. A position that says democracy is constituted by deliberative action is then undercut by its own starting point — a temporal (before/after) inconsistency. Option D captures this.
Why the other options are wrong:
A, B, E: The passage does not call deliberation irrational, useless or thoughtless — Desire is what makes deliberation possible.
C: Desire is the source of deliberation, not a substitute for it; the passage never says people act without thinking.
Cetking shortcut: 'Ante' = before (ante-date, ante-room). The only option dealing with timing/sequence is D.
Answer: D
Refer to the passage above ↑
Which of the following is true from the passage?
- AAuthor argues that democracy is bound to fail.
- BAuthor argues that Desire is primal.
- CAuthor argues for an end to primal desire so that an end to competition can come through.
- DAuthor argues - democracy demands are not reflexive
- EAuthor argues - democracy demands a reflexive reordering of preferences in a non-coercive manner.
Show answerHide answer
Answer: E ✓ official key
Approach: Specific detail — match an option to a sentence in the passage.
Solution: Sentence 1: "Deliberative democracy demands a reflexive (or reflection driven) reordering of preferences in a non-coercive manner." Option E reproduces this almost word for word.
Why the other options are wrong:
A: The author questions authenticity under coercion; never says democracy is bound to fail.
B: Desire is described as primordial, but that is not the claim being argued about democracy; E is the stated thesis.
C: The author says Desire makes deliberation possible; there is no call to end it.
D: Contradicts sentence 1 — democracy demands reflexive reordering.
Cetking shortcut: 'Which is true' with a near-verbatim option of the first sentence — take it after a quick check of the rest.

A Foucauldian discourse as used in the passage does NOT refer to :
- Adiscourse based on power.
- Bcommunity based discourse.
- Cstrategic discourse.
- Dunplanned discourse
- Enon-strategic discourse.
Show answerHide answer
Official CET key: C · Cetking's answer: E — see why below
Approach: NOT question — list what the passage attributes to Foucauldian discourse, then find the label it does not carry.
Solution: The passage says two separate things. (1) "A talk or a rhetoric, otherwise, is strategic and is employed with the intention of signalling certain information." (2) "The illocutionary force and the normative trappings of a Foucauldian discourse, while allowing identification with a community and differences with the others, do simultaneously pose through coercion a threat…" So Foucauldian discourse = power-based (normative force, coercion, discipline), community-based (identification with a community), and it works without a deliberate plan: the norms discipline thought on their own (non-strategic, unplanned). Strategy, the intentional signalling of information, is the mark of rhetoric. So Foucauldian discourse does NOT refer to strategic discourse.
Why the other options are wrong:
A: Power-based — its 'illocutionary force' and coercion are power.
B: Community-based — it allows 'identification with a community'.
D, E: Unplanned / non-strategic — fits: the discipline comes from norms, not from a speaker's intent.
Cetking shortcut: In NOT questions on dense passages, map each option to a phrase; the one that belongs to a different subject in the passage (here rhetoric) is the odd one.

According to the paragraph, ‘cans can often fetch considerable sums’ means the same as:
- AFrench Tonic is quite expensive in some parts of the world.
- Bcollectors consider carefully how much they are paying for a can of French Tonic.
- CTechnological innovation is sufficient to achieve sustainability
- DSome collectors will only drink French Tonic in exclusive stores.
- ECertain French Tonic cans are worth a lot of money as collectable items.
Show answerHide answer
Official CET key: D · Cetking's answer: E — see why below
Approach: Phrase meaning in context.
Solution: Para 1: "old French Tonic bottles and 'limited edition' cans can often fetch considerable sums from collectors, and there are even stores which deal exclusively in French Tonic products and memorabilia." To 'fetch a sum' = to be sold for that amount. So the phrase means certain cans are worth a lot of money as collectable items — option E. The official MahaCET key marks D, linking the phrase to the very next clause about exclusive stores; the passage, however, speaks of stores selling products and memorabilia, not of collectors drinking there.
Why the other options are wrong:
A: About the price of the drink, not of collectable cans.
B: Collectors paying 'carefully' is not the sense of 'fetch'.
C: Technological innovation/sustainability — unrelated to the passage.
D (official key): The exclusive-stores detail is in the passage, but it is about stores dealing in products and memorabilia, not collectors drinking.
Cetking shortcut: 'Fetch' + money = sell for. Match the option that keeps both 'cans' and 'collectors'.
Answer: D (official MahaCET key; the text-based meaning of the phrase is E)
Refer to the passage above ↑
According to the paragraph, the author uses ‘for good measure’ to emphasize the fact that:
- AThere is a lot of caffeine in French Tonic.
- BThe amount of caffeine in French Tonic is carefully measured.
- CThe extra caffeine improves the taste of French Tonic.
- DThe extra caffeine balances the amount found naturally in the cola extract.
- EThe extra caffeine is healthy for the drinkers of French Tonic.
Show answerHide answer
Answer: A ✓ official key
Approach: Idiom in context.
Solution: Para 3: "cola extract contains caffeine… and the French Tonic company adds extra caffeine for good measure." The idiom means 'in addition, as an extra'. The author stresses that caffeine is already present and more is added — so the drink has a lot of caffeine (and the next lines link this to repeat sales).
Why the other options are wrong:
B: Literal reading of 'measure'; the idiom does not mean careful measurement.
C: Taste is never mentioned.
D: 'Balance' is opposite — extra caffeine adds to, not balances, the natural amount.
E: Health benefit not claimed; the passage says the drink is hardly healthy.
Answer: A
Refer to the passage above ↑
According to the paragraph, ‘French Tonic has enjoyed phenomenal success’ suggests that the author:
- AThinks that the success of French Tonic is very strange.
- BBelieves that the success of French Tonic has been impressive.
- CThinks that the success of French Tonic is beyond explanation.
- DRather disapproves of the success of French Tonic.
- EConsiders the success of French Tonic to be undeserved.
Show answerHide answer
Answer: B ✓ official key
Approach: Tone through word choice.
Solution: "French Tonic has enjoyed phenomenal success worldwide" — phenomenal = extraordinary, remarkable. The author is describing the success as impressive (he even calls it 'amazing success' in para 2).
Why the other options are wrong:
A, C: 'Strange' / 'beyond explanation' — the author goes on to explain it (name, caffeine, marketing).
D, E: No disapproval or 'undeserved' judgement in this sentence.
Answer: B
Refer to the passage above ↑
Describing French Tonic’s marketing strategies as ‘enviable’ in the paragraph, the author means that:
- AThe strategies are based on envy.
- BFrench Tonic’s marketing staff is encouraged to be envious of each other’s ideas.
- CPeople are persuaded to buy French Tonic because they are envious of others.
- DRivals are envious of the French Tonic Company’s successful methods of marketing.
- EFrench Tonic’s marketing strategies are enviable.
Show answerHide answer
Answer: D ✓ official key
Approach: Word meaning, confirmed by the next sentences.
Solution: Para 4: "the company's enviable marketing strategies… Few other companies (arguably including P Tonic) have been able to match such marketing ploys." Enviable = arousing envy in others because it is so good. So rivals envy French Tonic's successful marketing.
Why the other options are wrong:
A: Strategies are not 'based on envy'.
B: Staff envying each other — not stated.
C: Customers buying out of envy — not stated.
E: Restates the word without explaining what the author means.
Cetking shortcut: An option that merely repeats the question's word (E) is almost never the 'meaning' answer.
Answer: D
Refer to the passage above ↑
It can be inferred from the last sentence of the passage that:
- AMost people would like to live in America.
- BMany people wish for a lifestyle like they imagine most Americans have.
- CDrinking French Tonic reminds a lot of people of visiting America.
- DLiving in the United States is a bit like living in a dream.
- EDrinking French Tonic is part of the American dream.
Show answerHide answer
Answer: B ✓ official key
Approach: Inference from the final sentence plus the one before it.
Solution: "French Tonic has somehow come to represent a vision of the United States that much of the rest of the world dreams about and aspires to. Perhaps drinking French Tonic brings people that little bit closer to the dream." The 'dream' is an imagined American way of life that people aspire to — so many people wish for a lifestyle like they imagine Americans have.
Why the other options are wrong:
A: 'Live in America' is too literal and too strong ('most people').
C: Nothing about remembering visits to America.
D: Says nothing about real life in the US.
E: The drink is a route to the dream, not a part of the 'American dream' idea.

Comparison between two countries becomes difficult because
A. the countries differ in their internal political systems.
B. each country has its own culture and natural resources which differ from those of others.
C. the countries with homogeneous backgrounds are many in number.
- AOnly A
- BOnly B
- COnly A and B
- DAll the three A, B and C
- EOnly C
Show answerHide answer
Answer: C ✓ official key
Approach: Check each statement against the first sentence.
Solution: "It is difficult to compare countries because various factors such as size, Culture, History, Geography, natural endowments, geopolitics and internal polity come into play."
A (different internal political systems) = internal polity ✔
B (own culture and natural resources) = culture, natural endowments ✔
C (many countries with homogeneous backgrounds) — not stated ✘
So only A and B.
Why the other options are wrong:
A, B alone: each misses one supported statement.
D, E: include C, which is not in the passage.
Answer: C
Refer to the passage above ↑
Which of the following have the Chinese identified as their pitfall(s) from their past?
A. Lack of orientation of Science and Technology towards economic growth.
B. Lack of mechanisms in their economic activities to promote use of Science and Technology.
C. Neglect of Science and Technology as a strategic measure for empowerment.
- AOnly A and B
- BOnly B and C
- COnly A and C
- DAll the three A, B and C
- EOnly A
Show answerHide answer
Answer: D ✓ official key
Approach: Match each statement to the 'lessons from past performance' sentences.
Solution: Para 3: (1) "failure to promote science and technology as strategic tools for empowerment" = C ✔ (2) "absence of mechanisms and motivations in their economic activity to promote dependence on science and technology" = B ✔ (3) "their scientific and technological efforts were not oriented… achievements were not converted into productive forces as they were too far removed from China's immediate economic and social needs" = A ✔. All three are stated.
Why the other options are wrong:
A, B, C, E: each leaves out at least one pitfall the passage lists.
Cetking shortcut: The passage lists three lessons in three consecutive sentences — when three statements map to three sentences, choose 'all three'.
Answer: D
Refer to the passage above ↑
Which of the following is/are the expected result/s of China’s new visions?
A. To augment peoples’ standard of living.
B. To tackle pressure effectively brought on by the population.
C. To utilize modern technology for bringing the latent power under control.
- AOnly A and B
- BOnly B and C
- COnly A and C
- DAll the three A, B and C
- EOnly B
Show answerHide answer
Official CET key: D · Cetking's answer: A — see why below
Approach: Match each statement to the 'Chinese vision is therefore aimed at…' sentence.
Solution: "The Chinese vision is therefore aimed at exploiting state-of-art science and technology to enhance the nation's overall power and strength, to improve the people's living standards, … and to effectively control and alleviate pressures brought on by population resources and the environment."
A (augment standard of living) ✔
B (tackle population pressure) ✔
C (use modern technology to harness the nation's power) — paraphrase of the first aim ✔
All three are expected results.
Why the other options are wrong:
A (Only A and B): misses the first aim — using modern S&T for national power.
B, C, E: each leaves out a stated aim.
Cetking shortcut: One sentence lists the aims — tick every option that maps to a clause of that sentence.
Answer: D
Refer to the passage above ↑
Which of the following is the essence of the contents of the passage?
- AEnormous population of the country can be positively utilized for developments.
- BScientific and Technological principles may not necessarily be instrumental in economic growth.
- CHarmonious development of a country can take place even in the absence of technology upgradation.
- DEconomic growth needs to be driven by science and technology
- EScientific innovations do not necessarily lead to any improvements in economic growth of a country
Show answerHide answer
Answer: D ✓ official key
Approach: Main idea — the claim repeated across paragraphs.
Solution: Para 2: growth "by relying on advances in science and technology is pivotal". Para 3: S&T "constitute premier productive forces… can propel economic and social development". The whole passage says economic growth needs to be driven by science and technology.
Why the other options are wrong:
A: Population is a pressure to alleviate, not a resource to use.
B, E: Contradict the passage — S&T is the engine of growth.
C: Contradicts the passage — development needs technology upgradation.
Cetking shortcut: Three of the five options deny the S&T–growth link; the passage asserts it — that leaves D.
Answer: D
Refer to the passage above ↑
According to the passage, China’s long-term goal in science and technology is to
- Acompletely eliminate dependence on agriculture.

- Crestrict technological development to civilian sectors only.
- Dfocus only on short-term economic gains.
- Eavoid investment in research and development.
Show answerHide answer
Answer: B ✓ official key
Approach: Specific detail — last sentence of the passage.
Solution: "…to enable parity in defense, science and technology with the advanced world." Also: "The aim is to bridge an overall gap with the advanced world."
Why the other options are wrong:
A: Agriculture is to be improved ('agricultural production'), not eliminated.
C: The passage emphasises defence technologies — opposite of 'civilian only'.
D: Targets run to 2020 and beyond — long-term, not short-term.
E: There is 'special emphasis on research and development' — opposite.

According to the passage, all of the following are not true, except:
- ATraditional theories failed to calculate the effects of global warming.
- BFall in temperatures in the Antarctic is in accordance with the traditional theories.
- CEffect of global warming is the maximum at the Poles.
- DEffect of global warming on Antarctica is on unexpected lines.
- EEffect of global warming on Antarctica is on expected lines.
Show answerHide answer
Answer: D ✓ official key
Approach: Decode the double negative — 'all are not true, except' means pick the one true statement.
Solution: Passage: "Traditional theories of climate change have held that the effects of global warming ought to be magnified at the Poles. Nonetheless… the Antarctic is definitely getting cooler." Antarctica is 'bucking the trend', the 'only one of Earth's seven continents to react differently'. So the effect on Antarctica is on unexpected lines — D is true.
Why the other options are wrong:
A: Theories did not 'fail to calculate' effects; they predicted magnification at the Poles.
B: Antarctic cooling goes against traditional theory.
C: Only the theory claims this; Antarctica is cooling, so not established as true.
E: Direct opposite of D.
Cetking shortcut: D and E are opposites — one of them is the true statement; 'bucking the trend' decides it.
Answer: D
Refer to the passage above ↑
According to the passage, it can be said that
- AAntarctica has become warmer than the other continents of the world.
- BAntarctica has become colder than the Earth over the last 35 years.
- CThe decade growth in temperature is much higher for Antarctica than the Earth itself.
- DThe average temperature rise for the decade 1979–1998 was more than the average rise in temperature over the last 100 years.
- EBoth the Arctic and Antarctic are getting cooler with global warming.
Show answerHide answer
Answer: B ✓ official key
Approach: Specific detail — test each option against the numbers in the passage.
Solution: "while temperatures in every other continent have risen over the past century, Antarctica has become appreciably colder over the past 35 years and continues to cool." Earth: +0.06°C a decade (100 years); Antarctic: −0.7°C a decade. So, compared with the warming Earth, Antarctica has become colder over the last 35 years — B.
Why the other options are wrong:
A: Opposite — Antarctica is cooling.
C: Antarctic 'decade growth' is negative (a fall of 0.7°C a decade).
D: Compares a 1979–1998 figure with a century-long average — not a like-for-like comparison, and the question asks about Antarctica; B is the statement the passage states directly.
E: The Arctic is getting warmer; only the Antarctic is cooling.
Answer: B
Refer to the passage above ↑
It can be inferred from the passage that:
- AOur knowledge and our theories about global climate change fails to explain what is happening across the globe.
- BIt is a matter of great contradiction that we failed to understand the full impact of global climatic change.
- CWe could not understand the importance of global climatic change.
- DIt was difficult for us to understand the full implication of global climatic change.
- EThe threat of global warming is accentuated due to what is happening in Antarctica.
Show answerHide answer
Answer: B ✓ official key
Approach: Inference — follow the passage's repeated word 'contradiction'.
Solution: The passage opens with pundits "blowing hot and cold", shows Antarctica cooling against traditional theory, says earlier sea-level estimates "will have to be suitably revised", asks "what is the mystery", and ends with "here's another contradiction" — icebergs breaking away in a cooling South. The inference: it is a matter of great contradiction that we have not understood the full impact of global climatic change — B.
Why the other options are wrong:
A: Too broad — the theories still explain the global warming trend; only Antarctica is the exception.
C: 'Importance' is never in doubt; the gap is in understanding effects.
D: Close, but drops the passage's key idea of contradiction — B states it.
E: The Antarctic cooling, if anything, runs against the warming trend; no 'accentuated threat' is drawn.
Cetking shortcut: When the passage literally uses a word (contradiction) twice, the inference option that carries it is usually the answer.
Answer: B
Refer to the passage above ↑
According to the passage, factors affecting the temperature profile of Arctic do not include
- Aocean currents.
- Bgreenhouse effects.
- Cdeforestation
- Dloosening of the ice sheets.
- Eglobal warming.
Show answerHide answer
Answer: C ✓ official key
Approach: NOT/EXCEPT detail — tick off every option the passage mentions.
Solution: Para 2: emissions waft to the North Pole "creating a greenhouse effect, warming the air and loosening the ice sheets"; "complex interplay of ocean currents" changes temperatures; the whole passage is about global warming. Deforestation is not mentioned anywhere.
Why the other options are wrong:
A, B, D, E: each is named in the passage as part of the temperature story.
Cetking shortcut: Outside knowledge is the trap in EXCEPT questions — the unmentioned item is the answer.
Answer: C
Refer to the passage above ↑

Approach: Specific detail.
Solution: "Climatologists are, however, unanimous… the Earth as a whole is becoming warmer — and largely due to increased human activity."
Why the other options are wrong:
A: Hot summers are an effect/symptom, not the cause.
C: Shrinking biodiversity is listed as an observed change, not a cause.
D, E: Narrower subsets; the passage names human activity.

- BIt looks as if it is going to rain this afternoon.
- CIt looks as if it is going to raining today afternoon.
- DIt looks like it is going to rain today's afternoon.
- EIt looks likes it is going to rain today afternoon.
Show answerHide answer
Answer: B ✓ official key
Approach: Spot the error in each option: verb form, idiom, time expression.
Solution: B: "It looks as if it is going to rain this afternoon." — correct linking phrase, correct 'going to + base verb', idiomatic time phrase.
Why the other options are wrong:
A, E: 'looks likes' — wrong verb form after 'it looks'.
C: 'going to raining' — needs base verb 'rain'; also 'today afternoon'.
D: 'today's afternoon' is not idiomatic — 'this afternoon'.
Cetking shortcut: 'Today morning/afternoon/evening' is always wrong — use 'this'.
Answer: B
Directions: From the following sentences, choose the grammatically correct sentence.
- AA belief that he is humble and being really humble is what makes him so likeable.
- BA belief that he is humble and being really humble are what makes him so likable.
- CBelieving that he is humble and really being humble is what makes him so likeable.
- DBelieving that he is humble and really being humble are what makes him so likable.
- EA beliefs that he is humble and being really humble are what makes him so likable.
Show answerHide answer
Answer: C ✓ official key
Approach: Parallelism first, then agreement.
Solution: The two subject parts must be in the same form: "Believing that he is humble and really being humble" — two gerunds, parallel. The pair is presented as one combined quality that makes him likeable, so it takes the singular 'is what makes'. ('Likeable' and 'likable' are both accepted spellings — spelling is not the issue.)
Why the other options are wrong:
A, B, E: 'A belief… and being' mixes a noun with a gerund — not parallel; E also has 'A beliefs'.
D: Parallel, but the plural 'are' clashes with the singular 'makes' in the same clause.
Cetking shortcut: Eliminate non-parallel options first (A, B, E), then choose between C and D on agreement with 'makes'.
Answer: C
Change the voice of the following sentence:
People believe that the committee will announce the results tomorrow.
- AIt is believed that the committee will announce the results tomorrow.
- BThe results are believed that the committee will announce tomorrow.
- CIt was believed that the committee will announce the results tomorrow.
- DIt is believed that the results will be announced by the committee tomorrow.
- EThe results will be believed to announce by the committee tomorrow.
Show answerHide answer
Answer: D ✓ official key
Approach: Passive of a reporting verb + that-clause.
Solution: Step 1: People believe → It is believed (tense stays present).
Step 2: the committee will announce the results → the results will be announced by the committee.
Combined: "It is believed that the results will be announced by the committee tomorrow."
Why the other options are wrong:
A: Only half the sentence changes voice.
B: 'The results are believed that…' — ungrammatical structure.
C: 'was believed' — wrong tense (original is present).
E: 'believed to announce' — wrong meaning and form; needs 'to be announced'.
Cetking shortcut: In 'change the voice' questions, the option that converts every active clause usually wins.

Directions: From the following sentences, choose the grammatically correct sentence.
- AI can understand my sister better than my mother.

- DI can understand my sister better than I can understand my mother.
- EI can understands my sister more than my mother.
Show answerHide answer
Answer: D ✓ official key
Approach: Ambiguous comparison.
Solution: "I can understand my sister better than my mother" has two readings: (i) better than I understand my mother, (ii) better than my mother understands my sister. D removes the doubt: "I can understand my sister better than I can understand my mother."
Why the other options are wrong:
A, B, C: Same ambiguity; B also uses 'more' where 'better' fits 'understand'.
E: 'I can understands' — modal must take base verb.
Cetking shortcut: In comparison questions, prefer the option that repeats the verb to make both sides clear.
Answer: D
Directions: From the following sentences, choose the grammatically correct sentence.
- AShe said that Raj had a fall last week and he had been injured.
- BShe said that Raj had fallen the previous week and he had injured.
- CShe said that Raj had had a fall last week and he was injured.
- DShe said that Raj had had a fall the previous week and he had been injured.
- EShe saids that Raj had a fall last week and he had been injured.
Show answerHide answer
Answer: D ✓ official key
Approach: Reported speech — shift tense back and change time words.
Solution: Direct: "Raj had a fall last week and he was injured." Reported after 'She said': had a fall → had had a fall; last week → the previous week; was injured → had been injured. Only D does all three.
Why the other options are wrong:
A: Keeps 'had a fall' and 'last week'.
B: 'he had injured' — no object; needs passive 'had been injured'.
C: Keeps 'last week'; 'was injured' not shifted.
E: 'She saids' — wrong verb form.
Cetking shortcut: Look for 'the previous week / the day before' — options keeping 'last week/yesterday' are out.
Answer: D
Directions: From the following sentences, choose the grammatically correct sentence.
- AIn speaking with the Minister, he denied that there were any payoffs involved in the deal.
- BWhile speaking with the Minister, we were informed that there were no payoffs in the deal.
- CWhile speaking with the Minister, the Minister denied that there were any payoffs in the deal.
- DIn speaking with the Minister, he denied to the journalists that there were any payoffs in the deal.
- EAt speaking with the Ministers, the Minister denied that there was any payoffs in the deal.
Show answerHide answer
Answer: B ✓ official key
Approach: Dangling modifier — who is doing the 'speaking'?
Solution: The subject right after the comma must be the person speaking with the Minister. In B: "While speaking with the Minister, we were informed…" — we were speaking with the Minister. Logical and grammatical.
Why the other options are wrong:
A, D: 'he' is unclear — 'he' (the Minister?) speaking with the Minister; 'In speaking' is also awkward here.
C: The Minister speaking with the Minister — illogical.
E: 'At speaking' is wrong; 'there was any payoffs' — agreement error.
Cetking shortcut: Read the -ing phrase and the first noun after the comma together; if they don't make sense as doer + action, reject.
Answer: B
Directions: From the following sentences, choose the grammatically correct sentence.
- AShe intended to get married to him, but then she goes and breaks relations with him.
- BShe intends to get married to him, but then she goes and breaks relations with him.
- CShe intended to get married to him, but then she went and broke relations with him.
- DShe intended to get married to him, but then she will go and break relations with him.
- EShe intended to get married to him, but then she will go and breaks relations with him.
Show answerHide answer
Answer: C ✓ official key
Approach: Tense consistency.
Solution: 'Intended' sets the time in the past, so the following actions must also be past: "She intended to get married to him, but then she went and broke relations with him."
Why the other options are wrong:
A: intended (past) + goes/breaks (present) — tense clash.
B: intends… goes and breaks — reads as a habitual present; not the completed past event the sentence narrates.
D: intended (past) + will go (future) — illogical.
E: 'will go and breaks' — tense clash and wrong verb form.
Answer: C
Directions: From the following sentences, choose the grammatically correct sentence.

- DIn the class, who do you think the teacher likes the most of all the students?
- EWho do you think the teachers likes the best of all students in the class?
Show answerHide answer
Answer: A ✓ official key
Approach: Pronoun case — who (subject) vs whom (object).
Solution: Strip the inserted clause 'do you think': the teacher likes ___ the most. The blank is the object of 'likes' → 'him/her' → whom. A: "Of all the students in the class, whom do you think the teacher likes the most?" — formally correct, with 'the most' for a superlative among many.
Why the other options are wrong:
B, C, D: 'who' used as object of 'likes'.
E: 'who' as object and 'the teachers likes' — agreement error.
Cetking shortcut: He/him test: if the answer would be 'him', use whom.

- DShe was promoted in 2009 to General Manager, Systems.
- EShe were promoted in 2009 to a General Manager, Systems post.
Show answerHide answer
Official CET key: D · Cetking's answer: B — see why below
Approach: Articles with designations + concision.
Solution: When a person is promoted, appointed or elected to a unique post, the title takes no article: "She was promoted in 2009 to General Manager, Systems." D does this cleanly and concisely.
Why the other options are wrong:
A: Grammatical but wordy ('to the position of'); D is the tighter standard form.
B, C: 'a General Manager, Systems post/position' — indefinite article before a unique designation; clumsy.
E: 'She were' — subject–verb agreement error.
Cetking shortcut: With 'promoted to / appointed as / elected', drop the article before a specific title.

- Awhen the passengers were starting to board
- Bwhen the passengers started boarding
- Cthan the passengers started boarding
- Dthan the passengers start boarding
- Ewhen the passengers had started boarding
Show answerHide answer
Answer: B ✓ official key
Approach: Fixed conjunction pair Hardly… when.
Solution: Structure: Hardly had + subject + past participle … when + simple past. "Hardly had the train arrived when the passengers started boarding."
Why the other options are wrong:
A: Past continuous 'were starting' — not the simple past this structure needs.
C, D: 'than' goes with 'No sooner', not 'Hardly'; D also keeps present 'start'.
E: Past perfect in the second clause — boarding came after arrival, so simple past.
Cetking shortcut: Hardly/Scarcely → when; No sooner → than.

Solution: Abase (verb) = to lower someone in dignity, rank or esteem. Degrade = to lower in rank or dignity — exact match.
Why the other options are wrong:
A: adjourn — postpone.
C: humble — near, but milder and also an adjective; degrade is the direct sense of 'lower in dignity'.
D: pacify — calm.
E: tablet — unrelated noun.

- Atable
- Bblue
- Cslur
- Dstatement
- Eweakness
Show answerHide answer
Answer: C ✓ official key
Approach: Collocation — which noun goes with 'on his character'?
Solution: "This is a slur on his character" — slur = an insinuation or remark that damages someone's reputation. 'A slur on' is the standard collocation.
Why the other options are wrong:
A: table — meaningless here.
B: blue — not a noun that fits.
D: statement — 'a statement on his character' is neutral and unidiomatic; the phrase implies damage.
E: weakness — would be 'in', not 'on', his character.
Cetking shortcut: Slur / slight / reflection / blot + on someone's character.

Solution: Efficiency describes functioning/management. "The administration of the state is efficient" — the running of the state is efficient.
Why the other options are wrong:
B, D, E: democracy, autocracy, plutocracy are forms of government, not things judged on efficiency.
C: policy — a policy is judged effective/sound; 'policy of the state is efficient' is unidiomatic.

Show answerHide answer
Answer: C ✓ official key
Approach: Meaning + agreement.
Solution: "The ___ of private limited companies is in the hands of its directors." We need a singular noun meaning 'running/control'. Management fits: control of the company rests with the directors.
Why the other options are wrong:
A, B: plural (managers, administrators) — disagree with 'is'; also people cannot be 'in the hands of' directors in this sense.
D: department — a unit, not control.
E: society — unrelated.
Cetking shortcut: Check the verb: 'is' rules out plural options instantly.

- E28
Show answerHide answer
Official CET key: A · Cetking's answer: C — see why below
Approach: Interleaved series — a +3 series with two odd terms (35, 40) inserted after every two terms.
Solution:
Mark the terms that clearly break the flow: 35 and 40.
Remaining terms: 7, 10, 13, __, 19, 22 → each term is +3.
13 + 3 = 16, and 16 + 3 = 19 confirms it.
Full series: 7, 10, [35], 13, 16, [40], 19, 22 — the inserted terms themselves rise by 5 (35 → 40).
Why the other options are wrong: 18, 23, 31, 28 do not keep the 13 → ? → 19 gap of +3, +3.
Cetking shortcut: When one or two terms are far out of line, strike them out first and read the remaining series.

Solution:
A spy must work in a clandestine (secret) way — secrecy is the defining trait of the job.
An accountant must be meticulous (careful, precise) — precision is the defining trait of that job.
Why the other options are wrong:
B: a furrier need not be rambunctious (noisy, unruly).
C: a lawyer is not defined by being ironic.
D: a shepherd need not be garrulous (talkative).

- BPrem is the maternal uncle of Arun
- CQadira is the maternal grandmother of Arun
- DChitra and zara are sisters
- EPrem is grandfather of Arun
Show answerHide answer
Answer: B ✓ official key
Approach: Build the family tree from the given links.
Solution:
Zara is the mother of Qadira; Chitra and Qadira are sisters → Zara is also Chitra's mother.
Prem is Zara's son → Prem is the brother of Chitra.
Arun is Chitra's son → Prem is the brother of Arun's mother = maternal uncle of Arun.
Why the other options are wrong:
A: Prem is Arun's uncle, not cousin.
C: Qadira is Arun's maternal aunt; Zara is the grandmother.
D: Zara is Chitra's mother.
E: Prem is one generation above Arun, not two.
Answer: B
If P + Q means P is the daughter of Q; P - Q means P is the brother of Q; P % Q means P is the father of Q and P x Q means P is the sister of Q. Which of the following means I is the niece of J?
- AJ - N % C x I
- BI x C - N % J
- CJ + M x C % I
- DI x C + N – J
- EN – C % M + I
Show answerHide answer
Answer: D ✓ official key
Approach: Decode each symbol and look for: I is female, I is the child of J's sibling.
Solution: Option D: I × C + N – J
I × C → I is the sister of C (I is female).
C + N → C is the daughter of N → I is also N's child.
N – J → N is the brother of J.
So I is the daughter of J's brother → I is J's niece.
Why the other options are wrong:
A: J – N % C × I → I is N's child, but I's gender is not fixed (could be nephew).
B: I × C – N % J → C is brother of N, N is father of J → I is J's aunt.
C: J + M × C % I → J is M's daughter, M is C's sister, C is I's father → I and J are cousins.
E: N – C % M + I → M is the daughter of I, so I is a parent (C's wife), not a niece of J.
Cetking shortcut: A niece needs a female marker on I — only options starting with 'I ×' (I is sister) qualify; check those first.

In the question below is given a statement followed by two conclusions numbered I and II. You have to assume everything in the statement to be true, then consider the two conclusions together and decide which of them logically follows beyond a reasonable doubt from the information given in the statement.
Give answer:
(1) If only conclusion I follows
(2) If only conclusion II follows
(3) If either I or II follows
(4) If neither I nor II follows and
(5) If both I and II follow.
The distance of 1000 km by road between Mumbai and Jafra will be reduced to 300 km by sea. This will lead to a saving of Rs.10 crores per annum on fuel.
Conclusions:
I. Transportation by sea is cheaper than by road
II. Fuel must be saved to the greatest extent
- A1
- B2
- C3
- D4
- E5
Show answerHide answer
Official CET key: B · Cetking's answer: A — see why below
Approach: A conclusion must follow from the statement itself — no outside assumptions.
Solution:
Conclusion I: The statement says only that the distance and the fuel bill fall. Total transport cost by sea (ships, ports, handling, time) is not compared with road, so 'sea transport is cheaper' is a broader claim than the data — it does not follow beyond reasonable doubt.
Conclusion II: The statement presents the fuel saving as the whole point of switching to sea transport, so the aim of saving fuel is taken as given → II follows.
Hence only II follows → option (2).
Why the other options are wrong: (1) and (5) need I, which compares total costs the statement never gives; (3) is for complementary pairs; (4) ignores the fuel-saving purpose.
Cetking shortcut: In CET, a conclusion that generalises (‘X is cheaper than Y’) from one specific case is usually rejected.
Answer: B
In the question below is given a statement followed by two conclusions numbered I and II.

- A1
- B2
- C3
- D4
- E5
Show answerHide answer
Official CET key: E · Cetking's answer: A — see why below
Approach: Statement–conclusion read in the setter's intended sense: the example is offered to illustrate the rule.
Solution:
Statement: organised people find time for rest; Rutuja, despite a very busy schedule, finds time for rest.
Conclusion I: Rutuja is presented as managing rest in spite of a heavy schedule — the hallmark of the organised person the first line describes → I is taken to follow.
Conclusion II: 'Very busy schedule' directly tells us she works hard → she is industrious → II follows.
Hence both follow → option (5).
Why the other options are wrong: (1) ignores the clear 'very busy schedule' clue for II; (2) ignores the link between the rule and the example; (3) applies only to complementary pairs; (4) rejects both stated clues.
Note: In a pure syllogism question, 'All organised → rest' cannot be reversed; this item is framed as a statement–conclusion, where the intended reading accepts I.

In a certain code, COMPUTER is written as PMOCRETU, how is DECIPHER written in that code?
- AICEDERHP
- BURETQMNL
- CFVNHQAER
- DICEDREHP
- EICEDPREH
Show answerHide answer
Answer: D ✓ official key
Approach: Split the word into two halves and reverse each half.
Solution:
COMPUTER = COMP | UTER → PMOC | RETU = PMOCRETU ✓
DECIPHER = DECI | PHER → ICED | REHP = ICEDREHP.
Why the other options are wrong: A (ICEDERHP) and E (ICEDPREH) misreverse the second half; B and C use letter shifts that the example does not show.
Cetking shortcut: If the coded word uses exactly the same letters, it is a position code — test 'reverse halves' first.

- E42379
Show answerHide answer
Official CET key: A · Cetking's answer: B — see why below
Approach: Letter → alphabet position; two-digit positions are reduced to their digit sum.
Solution:
HARYANA: H=8, A=1, R=18→1+8=9, Y=25→2+5=7, A=1, N=14→1+4=5, A=1 → 8197151 ✓
DELHI: D=4, E=5, L=12→1+2=3, H=8, I=9 → 45389.
Why the other options are wrong: 32167, 45321, 49723, 42379 do not match D=4, E=5 and the digit-sum rule for L.
Cetking shortcut: D=4, E=5 already leaves only A (45389) and C (45321); I=9 settles it.

What does the area marked 1 in the figure given below represent ?
Figure: Venn diagram of four overlapping circles labelled Honest, Advocates, Swimmers and Europeans, with regions marked P, A, Q, 1, 2, B, D, 4, 3, S, C, R.
- AAll Honest European swimmers
- BAll honest advocates who are swimmers
- CAll non- European advocates who are honest swimmers
- DAll non- Europeans who are honest swimmers
- EAll Honest European advocates who are swimmers
Show answerHide answer
Official CET key: C · Cetking's answer: E — see why below
Approach: Read which circles contain the region and which do not.
Solution:
Region 1 lies inside the Honest (yellow), Advocates (green) and Swimmers (olive) circles.
It lies just left of the Europeans (purple) circle — outside it (region 2 is the one inside all four).
So region 1 = honest advocates who are swimmers and NOT European.
Why the other options are wrong:
A: says European and omits advocates.
B: does not exclude Europeans (that covers regions 1 and 2).
D: omits advocates.
E: European advocates who are honest swimmers = region 2.
Cetking shortcut: For any region, list IN-circles and OUT-circles; the right option names both.

- A10
- B-10
- C-18
- D-32
- E-24
Show answerHide answer
Official CET key: C · Cetking's answer: A — see why below
Approach: Replace symbols, then apply BODMAS.
Solution:
Rules: × → –, + → ÷, – → ×, ÷ → +.
11 – 2 ÷ 700 + 70 × 50 becomes 11 × 2 + 700 ÷ 70 – 50
= 22 + 10 – 50
= –18.
Why the other options are wrong: 10 / –10 / –32 / –24 come from wrong substitution or from solving left to right without BODMAS.
Cetking shortcut: Rewrite the whole expression first, then compute — never substitute and calculate at the same time.

Approach: A strong argument is relevant, logical and not based on prejudice.
Solution:
I: 'sons are more intelligent than daughters' — a baseless gender stereotype → weak.
II: 'daughters get married and go away' — a social prejudice, and it does not justify giving less education → weak.
Neither argument is strong.
Why the other options are wrong: A, B, E treat a prejudiced argument as strong; C needs two strong, complementary arguments.

In a school, final selection list of the class 12th students who opted for extracurricular activities was posted in the corridor. In the list Vinay was ranked 18th from the top and 36th from the bottom among those who got selected. 12 students did not opt for any extracurricular activity and 7 were disqualified from it. How many students were there in the class ?
- A61
- B72
- C57
- D65

Approach: Count the digit 4 in the units place and the tens place separately.
Solution:
Units place: 4, 14, 24, …, 94 → 10 times.
Tens place: 40, 41, …, 49 → 10 times (44 counted again here — it has two 4s).
100 has no 4.
Total = 10 + 10 = 20.
Why the other options are wrong: 15 counts tens only partly; 25/32/35 over-count.
Cetking shortcut: For any digit 1–9 in 1 to 100, the count is always 20.

The question below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer:
Question : What is the cost of flooring a rectangular hall ?
Statement I: The difference between the length and breadth of the rectangle is 5 cm.
Statement II: The perimeter of the rectangular hall is 50 cm
Statement III: The cost of flooring 100 cm² area is Rs. 1000.
- AEither statement III alone or statements I and II together are sufficient.
- BOnly statement III is sufficient.
- COnly statement I and III is sufficient.
- DOnly statement II is sufficient
- EStatement I, II, and III together are sufficient.
Show answerHide answer
Answer: E ✓ official key
Approach: Cost of flooring = area × rate; area needs both length and breadth.
Solution:
I: L – B = 5 → one equation.
II: 2(L + B) = 50 → L + B = 25.
I + II: L = 15, B = 10 → area = 150 cm².
III: rate = Rs 1000 per 100 cm² → cost = 150 × 10 = Rs 1500.
All three statements are needed.
Why the other options are wrong: III alone has no area; I + II alone have no rate; any two statements leave one unknown.
Answer: E
Question below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer:
Question : If a rope is cut into three pieces of unequal length, what is the length of the shortest of these pieces of rope?
Statement I : The combined length of the longer two pieces of rope is 17 meters.

- AThe data in statements I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question.
- BThe data in statements II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question.
- CEither Statement I or Statement II alone is sufficient to answer the question.
- DThe data in both the statements I and II is not sufficient to answer the question.
- EThe data in both the statements I and II together is necessary to answer the question.
Show answerHide answer
Answer: D ✓ official key
Approach: Count unknowns vs independent equations.
Solution:
Let the pieces be x < y < z.
I: y + z = 17.
II: x + y = 15.
Together: 2 equations, 3 unknowns, total length not given.
Check: (7, 8, 9) and (6.6, 8.4, 8.6) both satisfy x + y = 15, y + z = 17, x < y < z — but the shortest piece differs.
Hence even both together are not sufficient.
Why the other options are wrong: A, B, C claim one statement alone works; E claims the pair is enough — it is not.

Show answerHide answer
Answer: C ✓ official key
Approach: Build the tree for six members.
Solution:
Q is the daughter of S and P → S is P's husband.
T is the brother of P's husband → T is S's brother.
U is T's mother → U is also S's mother.
Q is R's granddaughter; the only member left for the grandfather slot is R → R is U's husband, father of S and T.
So R is T's father.
Why the other options are wrong: R is one generation above T, so brother, son and nephew are out; uncle would need R to be a sibling of T's parent.

Answer: B ✓ official key
Approach: Fill the blanks so the series becomes a repeating block.
Solution:
Fill with a, a, n, a, n:
ananna | ananna | ananna
= ananna | ananna | ananna — the block 'ananna' repeats three times.
Why the other options are wrong: A has only 4 letters for 5 gaps; C, D, E break the repeating block.

Official CET key: C · Cetking's answer: D — see why below
Approach: Decode the known links, then choose the symbol that makes Q a male child of T's sibling.
Solution:
R ÷ S → R is the daughter of S.
S × T → S is the father of T.
So R and T are siblings (R is T's sister).
For Q to be T's nephew, Q must be the son of R → 'Q – R' (Q is son of R).
Q – R ÷ S × T → Q is the son of T's sister → nephew.
Why the other options are wrong:
A (+): Q would be R's wife.
B (×): Q would be R's father.
D (÷): Q would be R's daughter → niece, not nephew.
E: is not a single symbol.

Answer: 55 – 19.
Why the other options are wrong: B and E swap the elements; C and D come from sorting words alphabetically (A→Z) or moving all numbers at once.
Cetking shortcut: Once positions 1–2 are fixed (Step II), the second element from the left never changes.
Answer: A
Study the following information and answer the question that follows :
A word and number arrangement machine when given an input line of words and numbers rearranges them following a particular rule in each step. The following is an illustration of input and rearrangement.
Input: quick fire 15 28 39 war 19 yellow
Step I: yellow quick fire 15 28 39 war 19
Step II: yellow 15 quick fire 28 39 war 19
Step III: yellow 15 war quick fire 28 39 19
Step IV: yellow 15 war 19 quick fire 28 39
Step V: yellow 15 war 19 quick 28 fire 39
Step V is the last step of the above input.
Input : age die 72 53 35 hold goal 26
How many steps will be required to complete the rearrangement ?
- AThree
- BFour
- CFive
- DSix
- ETwo
Show answerHide answer
Answer: D ✓ official key
Approach: Input–output machine that places ONE element per step, alternating word (reverse alphabetical) and number (ascending).
Solution:
Example rule: yellow (step I), 15 (II), war (III), 19 (IV), then quick and 28 … final: yellow 15 war 19 quick 28 fire 39.
Words in reverse alphabetical order: hold, goal, die, age. Numbers ascending: 26, 35, 53, 72.
Input: age die 72 53 35 hold goal 26
Step I: hold age die 72 53 35 goal 26
Step II: hold 26 age die 72 53 35 goal
Step III: hold 26 goal age die 72 53 35
Step IV: hold 26 goal 35 age die 72 53
Step V: hold 26 goal 35 die age 72 53
Step VI: hold 26 goal 35 die 53 age 72 — final arrangement.
Why the other options are wrong:
Three/Four/Five: stop before 53 and 72 are in place. Two: far too few — one element moves per step.
Cetking shortcut: Count elements that are NOT already in their final position; here 6 of 8 need a move (age and 72 fall into place automatically), so 6 steps.

Read the information given below carefully and answer the question that follows :
In a particular college, sixty students were studious. Ten among them were also among the top sport performers. How many top sports performers were in the college ?
Statement A : Sixty percent of the top sports performers were not studious.
Statement B : All the top sports performers were not necessarily studious.
- AThe question can be answered by using the statement A alone but not by using the statement B alone
- BThe question can be answered by using the statement B alone but not by using the statement A alone.
- CThe question can be answered by using either of the statements alone
- DThe question can be answered by using both the statements together but not by either of the statements alone.
- EThe question cannot be answered on the basis of the two statements.
Show answerHide answer
Answer: A ✓ official key
Approach: Data sufficiency with overlapping groups (studious ∩ top sports performers).
Solution:
Studious and top sports performer (both) = 10.
Statement A: 60% of top sports performers are NOT studious ⇒ 40% of them are studious.
0.4x = 10 ⇒ x = 25 top sports performers. Sufficient.
Statement B: 'not necessarily studious' gives no number or ratio ⇒ x cannot be found. Not sufficient.
So A alone is sufficient, B alone is not.
Why the other options are wrong:
B/C: B carries no quantity. D: A already answers alone. E: A answers it.
Cetking shortcut: In DS, a statement with no number, ratio or exact relation (like B) is almost always insufficient.
Answer: A
Read the statements given below carefully and answer the question follows:
Statement I: The height of the triangle is 8 cm.
Statement II: The triangle is an isosceles.
Question : What is the area of a triangle ABC of base 12 cm ?
- AThe data in statements I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question.
- BThe data in statements II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question.
- CEither Statement I or Statement II alone is sufficient to answer the question.
- DThe data in both the statements I and II is not sufficient to answer the question.
- EThe data in both the statements I and II together is necessary to answer the question.
Show answerHide answer
Answer: A ✓ official key
Approach: Area of triangle = ½ × base × height; check which statement gives the height.
Solution:
Base = 12 cm (given).
Statement I: height = 8 cm ⇒ Area = ½ × 12 × 8 = 48 cm². Sufficient.
Statement II: 'isosceles' gives no length, so height is unknown. Not sufficient.
Hence I alone is sufficient, II alone is not.
Why the other options are wrong:
B/C: II gives no measurement. D: I clearly suffices. E: II is not needed.
Cetking shortcut: Base + height = area, for any triangle — the shape type is irrelevant.
Answer: A
Study the Statement and Conclusion given below carefully and select the most appropriate option :
Statement
A ≤ B < C;
A ≥ D;
C ≤ F
Conclusions
I. D < C
II. F ≥ D
- AOnly Conclusion I is true
- BOnly Conclusion II is true
- CEither of Conclusions I or II is true
- DNeither Conclusion I nor II is true
- EBoth Conclusions I and II are true
Show answerHide answer
Official CET key: A · Cetking's answer: D — see why below
Approach: Direct inequality chain; combine the statements through the common elements.
Solution:
Statements: A ≤ B < C, A ≥ D, C ≤ F.
Conclusion I (D < C): D ≤ A ≤ B < C ⇒ D < C. True.
Conclusion II (F ≥ D): F ≥ C > B ≥ A ≥ D ⇒ F > D strictly (the '<' between B and C makes it strict).
As per the exam convention, a '≥' conclusion follows only when equality is possible; here F can never equal D, so II is treated as not following.
Hence only Conclusion I is true.
Why the other options are wrong:
B: II is not accepted (only F > D is established) and I is true. C: 'either' needs a complementary pair — not the case here. D: I clearly follows. E: II does not follow under the convention.
Cetking shortcut: When a strict sign (< or >) sits anywhere in the chain, the result is strict — a '≥ / ≤' conclusion then fails under the CET/bank convention.
Answer: A
Identify the Odd One Out :
TPIL, RNJF, SOKL, YUQM, LATW
- ARNJF
- BSOKL
- CYUQM
- DLATW
- ETPIL
Show answerHide answer
Answer: A ✓ official key
Approach: Odd one out among letter groups — look for a simple common property (vowels).
Solution:
TPIL → contains I (vowel).
SOKL → contains O.
YUQM → contains U.
LATW → contains A.
RNJF → R, N, J, F — no vowel at all.
So RNJF is the odd one.
Why the other options are wrong:
SOKL, YUQM, LATW, TPIL each contain exactly one vowel, so they belong together.
Cetking shortcut: Before testing letter gaps, scan for vowels — it's the quickest check in odd-one-out letter groups.
Answer: A
In certain code 'FROZEN' is written as 'OFAPSG'. Then how would 'MOLTEN' be written in that code ?
- AOFPOMN
- BOFSMPN
- COFUMPN
- DOFUMON
- EOFUNPM
Show answerHide answer
Answer: C ✓ official key
Approach: Coding by reversing the word and shifting each letter +1.
Solution:
FROZEN reversed = N E Z O R F.
+1 to each: N→O, E→F, Z→A, O→P, R→S, F→G ⇒ OFAPSG ✓.
MOLTEN reversed = N E T L O M.
+1: N→O, E→F, T→U, L→M, O→P, M→N ⇒ OFUMPN.
Why the other options are wrong:
OFPOMN, OFSMPN, OFUMON, OFUNPM each break the +1 shift at one or more positions (T→U, L→M, O→P, M→N).
Cetking shortcut: Both words end in 'EN', so both codes start 'OF'; just code the remaining reversed letters T L O M → U M P N.
Answer: C
If :
agnoscrenia means poisonous spider
delanocrenia means poisonous snake
agnosdeery means brown spider
What could mean "black widow spider"?
- Adeeryclostagnos
- Bagnosdelano
- Cagnosvitriblunin
- Dtrymuttiagnos
- Eruetclogandelano
Show answerHide answer
Answer: C ✓ official key
Approach: Artificial-language coding: match repeated chunks to repeated words, and keep word order.
Solution:
agnos-crenia = poisonous spider; delano-crenia = poisonous snake ⇒ crenia = poisonous, agnos = spider, delano = snake.
agnos-deery = brown spider ⇒ deery = brown.
Order: the noun comes FIRST, the describing word after it (agnos + crenia, agnos + deery).
'black widow spider' must start with agnos and must not use crenia/deery/delano ⇒ agnos + vitriblunin.
Why the other options are wrong:
A: has deery (brown) and puts agnos last. B: delano = snake. D: agnos at the end — wrong word order. E: delano (snake), no agnos.
Cetking shortcut: Fix the known roots first, then use word ORDER to separate the last two candidates.
Answer: C
Choose the pair that best represents a similar relationship to the one expressed in the original pair of words.
DEPENDABLE : CAPRICIOUS
- Afallible : cantankerous
- Bincorrigible : guilty
- Ccapable : inept
- Dmalleable : limpid
- Eerasable : obtuse
Show answerHide answer
Answer: C ✓ official key
Approach: Word analogy — DEPENDABLE and CAPRICIOUS are antonyms.
Solution:
Dependable = reliable, consistent. Capricious = unpredictable, changing on a whim. So the pair is opposites.
capable (able, competent) : inept (incompetent) — also opposites.
Why the other options are wrong:
fallible : cantankerous — unrelated (liable to err / bad-tempered). incorrigible : guilty — not opposites. malleable : limpid — unrelated (pliable / clear). erasable : obtuse — unrelated.

Raman facing North and moves 20 km, then he turned to his right and moves 20 km and then he moves 10 km in North-East, then he turned to his right and moves 20 km and then he turned to his right and moves 20 km, and again he turned to his left and moves 20 km. Now in which direction is Raman facing ?
- ASouth-East
- BNorth-West
- CNorth-East
- DSouth- West
- ENorth
Show answerHide answer
Answer: A ✓ official key
Approach: Direction sense — track only the facing direction through each turn.
Solution:
Start facing North; moves 20 km North.
Turns right ⇒ East (20 km).
Moves 10 km North-East ⇒ now facing North-East.
Turns right (90°) from NE ⇒ South-East (20 km).
Turns right from SE ⇒ South-West (20 km).
Turns left from SW ⇒ South-East (20 km).
Final facing direction: South-East.
Cetking shortcut: Only the turns matter for facing direction — ignore all distances.

Each of P, Q, T, A and B have different heights. T is taller than P and B but shorter than A and Q. P is not the shortest, determine who is the tallest in the group ?
- AA
- BQ
- CEither P or B
- DP
- EEither A or Q
Show answerHide answer
Answer: E ✓ official key
Approach: Ranking by comparison — split people into 'taller than T' and 'shorter than T'.
Solution:
T is taller than P and B ⇒ P, B are below T.
T is shorter than A and Q ⇒ A, Q are above T.
Order: {A, Q} > T > {P, B}. 'P is not the shortest' ⇒ B is shortest, but nothing compares A with Q.
So the tallest is either A or Q.
Why the other options are wrong:
A alone / Q alone: A vs Q is never compared. Either P or B / P: both are shorter than T.

Approach: Multiplicative series with multipliers rising by 1 each step.
Solution:
Multipliers: ×0.5, ×1.5, ×2.5, ×3.5, ×4.5.
4 × 0.5 = 2
2 × 1.5 = 3
3 × 2.5 = 7.5 ✓
7.5 × 3.5 = 26.25 ✓
26.25 × 4.5 = 118.125 ✓
Cetking shortcut: Find a ratio from the known end: 118.125 ÷ 26.25 = 4.5, 26.25 ÷ 7.5 = 3.5 ⇒ multipliers fall by 1 going back ⇒ ?: 7.5 ÷ 2.5 = 3.

Study the following information carefully and answer the question that follows :
Each of the six friend - A, B, C, D, E and F - scored different marks in an examination. C scored more than only A and E. D scored less than only B. E did not score the least. The one who scored the third highest marks scored 81 marks. E scored 62 marks.
The person who scored the maximum scored 13 marks more than F's marks. Which of the following can be D's score ?
- A81
- B67
- C89
- D78
- E75
Show answerHide answer
Answer: C ✓ official key
Approach: Ranking puzzle — fix positions from 'more than only' / 'less than only' clues, then use the given marks.
Solution:
C scored more than only A and E ⇒ C is 4th (two people below him).
D scored less than only B ⇒ B is 1st, D is 2nd.
E did not score the least ⇒ E is 5th, A is 6th. Remaining F is 3rd.
3rd highest = F = 81. E = 62.
Maximum (B) = F + 13 = 94.
D lies between B and F: 81 < D < 94 ⇒ only 89 fits.
Why the other options are wrong:
81: that is F's score (all scores are different). 67, 78, 75: below F's 81, but D is 2nd.
Cetking shortcut: 'More than only X and Y' = exactly two below; 'less than only B' = exactly one above — place these first.
Answer: C
In the question below, the statement is followed by two assumptions numbered I and II. Decide which of the assumptions is implicit in the statement.
Statement:
Market trends are changing continuously and with increasing competitiveness, the consumer demands with respect to the prices and quality are gradually increasing.
Assumptions:
I. The consumers did not care for the prices and quality earlier.
II. Market competitiveness is not favourable for the consumer.
- Aonly assumption 'I' is implicit.
- Bonly assumption 'II' is implicit.
- Ceither assumption I or II is implicit.
- Dneither I nor II assumption is implicit.
- Eif both I and II assumptions are implicit.
Show answerHide answer
Answer: D ✓ official key
Approach: Statement–assumption: an assumption must be something the statement takes for granted.
Solution:
Statement: competition is rising and consumer demands on price and quality are 'gradually increasing'.
I: 'Consumers did not care earlier' — 'increasing' means demands were lower before, not absent. Too extreme ⇒ not implicit.
II: 'Competitiveness is not favourable for consumers' — the statement suggests consumers are gaining (they demand more); nothing says competition hurts them ⇒ not implicit.
Neither assumption is implicit.
Why the other options are wrong:
A/E: I is an exaggeration of 'increasing'. B/E: II contradicts the tone of the statement. C: 'either' needs I and II to be complementary — they are not.
Cetking shortcut: Words like 'did not care at all' convert 'more' into 'none' — reject such extreme assumptions.

Approach: Opposite-letter (reverse alphabet) coding: each letter is replaced by its pair that sums to 27.
Solution:
C(3)→X(24), O(15)→L(12), M(13)→N(14), B(2)→Y(25) … sum 27 each time ⇒ opposite-letter code.
ALLITERATION: A→Z, L→O, L→O, I→R, T→G, E→V, R→I, A→Z, T→G, I→R, O→L, N→M.
Code: ZOORGVIZGRLM.
Why the other options are wrong:
ZOOGIMLRGVZL, MRLZOOGIVZPT, LOOPRVITZQME, POOBLZRITQNV — each breaks the A↔Z, L↔O pairing at the very first letters.
Cetking shortcut: Remember the opposite pairs (A-Z, B-Y … M-N); A→Z and L→O already leave only option A.

Answer: B ✓ official key
Approach: Alternating operations series: ×2, −8.
Solution:
14 × 2 = 28
28 − 8 = 20
20 × 2 = 40
40 − 8 = 32
32 × 2 = 64
64 − 8 = 56
Cetking shortcut: Every second term doubles (14, 20, 32 → 28, 40, 64); the next step is the −8 one.

- AL
- BS
- CM
- DT
- EV
Show answerHide answer
Answer: B ✓ official key
Approach: Alphabet manipulation — reverse, delete vowels, then count position.
Solution:
Reversed: Z Y X W V U T S R Q P O N M L K J I H G F E D C B A.
Delete A, E, I, O, U ⇒ Z Y X W V T S R Q P N M L K J H G F D C B (21 letters).
15th from the right = (21 − 15 + 1) = 7th from the left.
Z(1) Y(2) X(3) W(4) V(5) T(6) S(7).
Why the other options are wrong:
L, M, T, V are at other positions (T is 6th, V 5th from left).
Cetking shortcut: n-th from right = (total − n + 1)-th from left; 21 − 15 + 1 = 7.

Answer: D ✓ official key
Approach: Circular seating (6 persons, facing centre); fix the opposite pairs first.
Solution:
F is opposite E, and F sits between A and D ⇒ A and D are F's two neighbours.
C is next to E (on E's right) and opposite A.
Seats 1–6: E = 1, F = 4. A and D take seats 3 and 5.
If C = 2 (beside E), A = 5 (opposite), D = 3, B = 6.
A's neighbours: seat 4 (F) and seat 6 (B).
(With C on the other side the figure is a mirror — A's neighbours are still B and F.)
Why the other options are wrong:
F and D: D is on F's other side, not next to A. E and C / E and F: C sits opposite A and E is two seats away. B and D: D is not adjacent to A.
Cetking shortcut: A's neighbours always include F (F is between A and D); only option D has F with a person other than D or E.

Lihaan walks 8m towards south from his office to reach park. Then takes a left and walks 15m to reach traffic signal. Then he turns 90 degree in anti-clock wise direction and walks 8m to reach a coffee shop. From the coffee shop he takes left and walks 8m to reach home.
What is the shortest distance between Lihaan's office and Traffic signal?
- A30 m
- B25 m
- C17 m
- D15 m
- E22 m
Show answerHide answer
Answer: C ✓ official key
Approach: Direction sense with coordinates; shortest distance by Pythagoras.
Solution:
Take office = (0, 0).
8 m South ⇒ park = (0, −8).
Facing South, a left turn = East; 15 m ⇒ traffic signal = (15, −8).
Office to signal: √(15² + 8²) = √(225 + 64) = √289 = 17 m.
Cetking shortcut: 8–15–17 is a Pythagorean triplet — spot it and answer instantly.
Answer: C
Refer to the passage above ↑
Park is in which direction with respect to Lihaan's Home?
- ASouth-West
- BSouth
- CNorth-West
- DNorth
- EEast
Show answerHide answer
Answer: A ✓ official key
Approach: Direction sense — plot all points, then compare park and home.
Solution:
Office (0, 0) → park (0, −8) → signal (15, −8).
At the signal he faces East; 90° anticlockwise ⇒ North; 8 m ⇒ coffee shop (15, 0).
Facing North, left = West; 8 m ⇒ home (7, 0).
Park (0, −8) relative to home (7, 0): 7 m West and 8 m South ⇒ South-West.
Why the other options are wrong:
South/North/East: park is both west and south of home, so a pure direction is wrong. North-West: park is lower (south), not north.
Cetking shortcut: Direction of X w.r.t. Y = look from Y towards X; here both x and y decrease ⇒ South-West.

Show answerHide answer
Official CET key: D · Cetking's answer: C — see why below
Approach: Input–output: words placed two at a time alphabetically, numbers two at a time in descending order, alternating.
Solution:
Rule from the illustration: odd steps bring the next TWO words in alphabetical order to the front block; even steps bring the next TWO numbers in descending order; everything else keeps its original order.
New input: Oral 11 Micy 25 Pink 47 81 Pick 49 Vineet 16 Neenu
Words (A→Z): Micy, Neenu, Oral, Pick, Pink, Vineet. Numbers (high→low): 81, 49, 47, 25, 16, 11.
Step I: Micy Neenu Oral 11 25 Pink 47 81 Pick 49 Vineet 16
Step II: Micy Neenu 81 49 Oral 11 25 Pink 47 Pick Vineet 16
Step III: Micy Neenu 81 49 Oral Pick 11 25 Pink 47 Vineet 16
Step IV: Micy Neenu 81 49 Oral Pick 47 25 11 Pink Vineet 16
Step V: Micy Neenu 81 49 Oral Pick 47 25 Pink Vineet 11 16
Step VI: Micy Neenu 81 49 Oral Pick 47 25 Pink Vineet 16 11
In Step III: … 81 49 Oral Pick … ⇒ Oral is between 49 and Pick.
Why the other options are wrong:
Pink: comes after Pick, near 47. 11: after Pick. Vineet: still at the far end in Step III. 49: one of the two named terms itself.
Cetking shortcut: Only Steps I–III are needed: after Step II (81 49) the next words are Oral and Pick, so Oral lands right after 49.

New input: Oral 11 Micy 25 Pink 47 81 Pick 49 Vineet 16 Neenu
Words (A→Z): Micy, Neenu, Oral, Pick, Pink, Vineet. Numbers (high→low): 81, 49, 47, 25, 16, 11.

Step V: Micy Neenu 81 49 Oral Pick 47 25 Pink Vineet 11 16
Step VI: Micy Neenu 81 49 Oral Pick 47 25 Pink Vineet 16 11
In Step V: … Oral Pick 47 25 Pink … ⇒ 47 and 25 sit next to each other ⇒ zero elements between them.
Why the other options are wrong:
Two, Three, Four, Five: all assume 25 and 47 are still at their input positions; by Step IV they were placed together as the second number pair.
Cetking shortcut: 47 and 25 are the 3rd and 4th largest numbers — they move together in Step IV and stay adjacent afterwards.

Official CET key: D · Cetking's answer: B — see why below
Approach: Linear order puzzle — build the fixed block first, then slide it.
Solution:
Q came immediately before P (no one between them, Q first) and V just before Q ⇒ block V Q P; S immediately after P ⇒ block V Q P S.
Three persons between R and S ⇒ R is 4 places before S (or after it).
Try S = 4: R would be at 0 or 8 — impossible.
S = 5 (V2 Q3 P4 S5): R = 1, then T (one between R and T) = 3 — taken. ✗
S = 6 (V3 Q4 P5 S6): R = 2, T = 4 — taken. ✗
S = 7 (V4 Q5 P6 S7): R = 3, T = 1 (5 is taken) ✓, U = 2.
Final order: T, U, R, V, Q, P, S.
First person: T.
Why the other options are wrong:
Q: Q is 5th. R: R is 3rd. S: S is last. P: P is 6th.
Cetking shortcut: Four people form one rigid block (V Q P S) in a line of 7 — only 4 positions to test.

Approach: Use the final order from the arrangement.
Solution:
Q came immediately before P (no one between them, Q first) and V just before Q ⇒ block V Q P; S immediately after P ⇒ block V Q P S.
Three persons between R and S ⇒ R is 4 places before S (or after it).
Try S = 4: R would be at 0 or 8 — impossible.
S = 5 (V2 Q3 P4 S5): R = 1, then T (one between R and T) = 3 — taken. ✗
S = 6 (V3 Q4 P5 S6): R = 2, T = 4 — taken. ✗
S = 7 (V4 Q5 P6 S7): R = 3, T = 1 (5 is taken) ✓, U = 2.
Final order: T, U, R, V, Q, P, S.
R is 3rd, Q is 5th ⇒ only V (4th) is between them ⇒ 1 person.
Why the other options are wrong:
4, 3, 2, 5: come from a wrong order; positions 3 and 5 have exactly one place between them.
Cetking shortcut: Persons between positions a and b = |a − b| − 1 = 5 − 3 − 1 = 1.

Approach: Use the final order from the arrangement.
Solution:
Q came immediately before P (no one between them, Q first) and V just before Q ⇒ block V Q P; S immediately after P ⇒ block V Q P S.
Three persons between R and S ⇒ R is 4 places before S (or after it).
Try S = 4: R would be at 0 or 8 — impossible.

S = 7 (V4 Q5 P6 S7): R = 3, T = 1 (5 is taken) ✓, U = 2.
Final order: T, U, R, V, Q, P, S.
R is 3rd ⇒ the person just before R (2nd) is U.
Why the other options are wrong:
P, Q, S: all come after R (positions 6, 5, 7). T: T is 1st, two places before R.

Answer: B ✓ official key
Approach: Odd figure out — check whether each letter is a mirror image or a rotated letter.
Solution:
(1) Я = mirror image of R.
(3) mirror image of Q (tail turns to the left).
(4) Ƨ = mirror image of S.
(5) mirror image of Z.
(2) is G turned upside down (rotated 180°) — its bar/hook is at the top, whereas a mirror G would keep the bar at the lower half.
So figure (2) is different.
Why the other options are wrong:
Figures 1, 3, 4, 5 are all plain lateral (mirror) images of R, Q, S, Z.
Cetking shortcut: In 'mirror letters' sets, check where the cross-bar/tail sits — a rotated letter moves it top↔bottom, a mirror only left↔right.

Approach: Figure series — two changes at once: the flag-stick rotates 90° clockwise each step, and the count goes 1, 1, 2, 2, 3, 3.
Solution:
A: 1 vertical stick, flag at top. B: 1 horizontal stick, flag at the right end hanging down (A turned 90° clockwise).
C: 2 sticks, flag at bottom. D: 2 sticks, flag at left. E: 3 sticks, flag at top.
Next: 3 sticks, rotated 90° clockwise from E ⇒ horizontal sticks with the flag at the RIGHT end, hanging below the line — same orientation as B.
Figure 1 shows exactly this.
Why the other options are wrong:
2 and 5: four sticks. 3: flags above the line (wrong orientation). 4: flags placed away from the end / wrong side.
Cetking shortcut: Figures two apart (A, C, E or B, D) are 180° apart; so the next figure copies B's orientation with three sticks.

Answer: C ✓ official key
Approach: Figure series with a repeating cycle.
Solution:
Figure E is identical to figure A ⇒ the series repeats every 4 figures: A, B, C, D, A(=E), …
So the next figure must be the same as B.
Answer figure 3 is an exact copy of B (same two symbols, same orientation and hooks).
Why the other options are wrong:
1, 2, 4, 5: each differs from B in the shape or orientation of at least one of the two symbols.
Cetking shortcut: Whenever the last problem figure equals an earlier one, simply copy the figure that came after it.

Approach: Figure classification — identify what the three left figures share.
Solution:
Each left figure: a single straight line with ONE small UNSHADED SQUARE on it (its position and the line's angle vary).
(b) is a line with one unshaded square on it ⇒ same type.
Why the other options are wrong:
(a) has a triangle. (c) square is shaded. (d) has a circle. (e) has two squares.
Cetking shortcut: Ignore the angle/position of the line — they vary in the given figures, so they can't be the rule.

Approach: Figure analogy — every PAIR of matching parts in A merges into ONE part in B.
Solution:
A → B: the two V's (top and bottom) join into a diamond; the two curved brackets join into a lens/oval at the bottom; the two small squares become one square at top-right.
C: the ∪ and ∩ join into a rounded rectangle (left); the two small circles become one circle (top-right); the two side lines join into one horizontal line at the bottom, keeping the circle where they met.
Figure 3 shows rounded rectangle + one small circle at top-right + a line with a circle at the bottom.
Why the other options are wrong:
1: keeps the crossing lines unmerged. 2: puts the oval inside an extra shape and loses the bottom line. 4: keeps brackets/circles separate. 5: doubles the line and circle.

Approach: Figure analogy — count-based change: the number of triangles doubles and half of them turn black.
Solution:
A: 5 circles + 2 white triangles (7 symbols).
B: 3 circles + 4 triangles (2 black, 2 white) — two circles became triangles; triangles doubled 2 → 4, and 2 of the 4 are black.
C: 7 circles + 2 white triangles (9 symbols).
D should have: 4 triangles (2 black + 2 white) and 5 circles.
Figure 1: Δ ▲ ∇ / ▼ ○ ○ / ○ ○ ○ ⇒ 4 triangles (2 black, 2 white), 5 circles ✓.
Why the other options are wrong:
2: 4 triangles but all black. 3: no triangles. 4: 3 white triangles, none black. 5: 5 triangles.
Cetking shortcut: When symbols just look 'reshuffled', count each symbol type and colour in A and B — the counts usually carry the rule.

Approach: Figure analogy — the cross-bar and the wavy line rotate by different amounts, and the fork end becomes an arrow.
Solution:
A → B: the wavy line turns 45° clockwise (its black end goes from left to top-left, white end from right to bottom-right).
The straight bar turns 135° anticlockwise (ball: top → bottom-left; forked end: bottom → top-right) and the fork becomes an arrow-head.
C: bar from top-left (T-end) to bottom-right (fork); wavy line from bottom-left (white end) to top-right (black end).
Apply the rule: wavy line 45° clockwise ⇒ horizontal, white end left, black end right. Bar 135° anticlockwise ⇒ vertical, fork (now arrow) at top, T-end at bottom.
Figure 2 matches: vertical bar with arrow up and T-base, horizontal wave with black hump at the right end.
Why the other options are wrong:
1: fork not changed into an arrow. 3 and 5: wave colours on the wrong ends. 4: bar horizontal and wave vertical — the rotation is wrong.
Cetking shortcut: Track one marked end of each element (black end, fork end) rather than the whole figure.

Approach: Common-property pair — find what both given figures share.
Solution:
Hexagon: divided by one vertical and one horizontal line into 4 EQUAL parts, one part shaded.
Four-petal flower: 4 equal petals, one shaded.
Rule: a figure divided into 4 identical parts with exactly one part shaded.
Figure 3: the concave shape is cut by a vertical and a horizontal line into 4 equal quarters, one shaded ✓.
Why the other options are wrong:
1: 4 horizontal bands of unequal size. 2: diagonals of a trapezium give unequal triangles. 4: diamond parts are unequal. 5: pencil shape parts are unequal.
Cetking shortcut: Check 'equal parts' — most distractors also have one shaded part but unequal divisions.

Approach: Common-property pair — 3×3 symbol grids with a fixed repetition pattern.
Solution:
Grid 1: three symbols appear twice (star, hour-glass, bell) and three appear once — and the pairs sit in the SAME cells: top-middle = top-right; top-left = middle-right; centre = bottom-left.
Grid 2: N at top-middle and top-right; flower-cross at top-left and middle-right; S at centre and bottom-left — the same pattern.
Figure 3: double-square at top-middle & top-right; pentagon at top-left & middle-right; flower-cross at centre & bottom-left ✓.
Why the other options are wrong:
1: one cell is empty. 2, 4, 5: repeated symbols sit in other cells / repeat a different number of times.
Cetking shortcut: Mark the three repeated pairs in one given grid; check only those cell positions in the options.

Approach: Common-property pair — nested polygons with consecutive side counts, plus an outside symbol copying the middle shape.
Solution:
Figure 1: pentagon ⊃ square ⊃ triangle (5, 4, 3) — outside small diamond (4) = middle shape.
Figure 2: diamond ⊃ pentagon ⊃ hexagon (4, 5, 6) — outside small pentagon (5) = middle shape.
Rule: three nested shapes with consecutive sides; the outside symbol has the same sides as the MIDDLE one.
Figure 2: hexagon ⊃ pentagon ⊃ square (6, 5, 4) with an outside pentagon (5) ✓.
Why the other options are wrong:
1: outside hexagon ≠ middle square. 3: hexagon–square–triangle is not consecutive. 4: outside triangle ≠ middle shape. 5: outside square ≠ middle pentagon.
Cetking shortcut: Look at the small outside symbol first — it must match the middle shape; that alone leaves option 2.

Answer: D ✓ official key
Approach: Counting triangles — group by type (tips, halves, centre-based, big).
Solution:
The star is two big triangles; three lines run from three star points through the centre, cutting three of the six tips in half.
Small half-tips: 3 tips × 2 = 6
Whole tips (all 6 star points): 6
Triangles with one vertex at the centre and one at a lower star point (a cut tip + adjoining piece): 6
Triangle on the bottom side of the upright big triangle with its apex at the centre: 1
Halves of big triangles cut by the lines (upright triangle cut by 2 lines = 4 halves, inverted cut by 1 line = 2 halves): 6
Big triangles: 2
Total = 6 + 6 + 6 + 1 + 6 + 2 = 27.
Cetking shortcut: Count systematically by size; the 6 'half big triangles' are the ones most often missed.

Approach: Counting squares on a 5×5 unit layout — count by side length.
Solution:
Treat the outer square as 5 × 5 units; two full vertical and two full horizontal lines plus an inner 3 × 3 square.
Side 1: 9 cells of the inner 3 × 3 grid + 4 small squares in the middle of each outer side = 13
Side 2: 4 inside the inner square (2 × 2 blocks) + 4 corner squares of the outer frame = 8
Side 3: the inner square + 4 squares of side 3 anchored at each outer corner = 5
Side 5: the outer square = 1
Total = 13 + 8 + 5 + 1 = 27.
Cetking shortcut: Count by size (1, 2, 3, …) — never by 'pieces', which double-counts.

Approach: Figure analogy — the whole figure rotates 90° anticlockwise and black ↔ white.
Solution:
A: top black dot, left white rectangle, right white triangle, bottom black trapezium.
Rotate 90° anticlockwise: top→left, left→bottom, bottom→right, right→top; then swap colours.
B: left white dot, bottom black rectangle, right white trapezium, top black triangle ✓.
C: top white parallelogram, left black triangle (pointing in), right black dot, bottom white pentagon.
Rotate + swap ⇒ left black parallelogram, bottom white triangle (pointing up, towards the circle), right black pentagon, top white dot.
Figure 5 matches.
Why the other options are wrong:
1: colours swapped but the figure is not rotated. 2: bottom triangle points away from the circle. 3 and 4: the dot stays black, so colours are not swapped.

Approach: Figure analogy — the frame turns 45°, the arrow moves 90° anticlockwise and the dot-line moves 45° anticlockwise.
Solution:
A → B: the diamond frame becomes an upright square (45° turn).
Arrow: from the left point (pointing in) to the bottom side (pointing in) — 90° anticlockwise.
Dot-line: from towards the right point to towards the top-right corner — 45° anticlockwise.
C: arrow from the top point, dot-line towards the left point.
D: upright square; arrow 90° anticlockwise ⇒ from the left side pointing right; dot-line 45° anticlockwise ⇒ towards the bottom-left corner.
Figure 3 matches.
Why the other options are wrong:
1: arrow comes from the top-left corner. 2 and 4: frame is still a diamond. 5: dot-line goes straight down, not to the corner.

Approach: Common-property pair — the bottom-left symbol is the top-right symbol turned upside down (mirror + water image = 180° rotation).
Solution:
In both given squares, the diagonal splits the square; the symbol in the lower-left half is the upper-right symbol rotated by 180°.
Figure 3: the upper-right 'M-like' zig-zag appears in the lower-left as a 'W', i.e. rotated 180° ✓.
Why the other options are wrong:
1: the symbol is copied unchanged. 2, 4, 5: the lower symbol is only a single mirror/water image (or differently shaded), not a 180° turn of the upper one.

Approach: Common-property pair — dot figures: same number of dots in an unsymmetrical (scattered) layout.
Solution:
Figure 1: 5 dots, arranged with no line of symmetry.
Figure 2: 5 dots, again with an irregular scattered layout (the dots have only shifted positions).
Rule: exactly 5 dots in an irregular, non-patterned arrangement.

Why the other options are wrong:
1: 5 dots but a symmetric T-shape. 3: 6 dots. 4: 5 dots but the symmetric dice-five/X pattern. 5: 6 dots.

Answer: D ✓ official key
Approach: Figure series (odd one out) — letters placed clockwise in alphabetical order.
Solution:
A: B (top) → C (right) → D (bottom) → E (left) — clockwise, consecutive.
B: G → H → I → J clockwise.
C: K → L → M → N clockwise.
E: T → U → V → W clockwise.
D: P (top), O (right), Q (bottom), R (left) — clockwise reads P, O, Q, R; for the pattern it should be O, P, Q, R.
So figure D (option 4) does not belong.
Why the other options are wrong:
Figures A, B, C, E all follow the clockwise consecutive order starting from the top.

Approach: Grouping figures by the direction of the curved lines inside.
Solution:
Curves bending inward towards the centre (back-to-back arcs): 1, 2, 5.
Curves bulging outward, forming a rounded centre: 3, 7, 8.
Straight lines fanning out from one point: 4, 6, 9.
Grouping: 1,2,5 ; 3,7,8 ; 4,6,9.
Why the other options are wrong:
B, C, D, E: each mixes inward-curve figures with outward-curve or fan figures.
Cetking shortcut: The fan group (4, 6, 9) is easiest to spot — options A and C have it; then check the curve direction in 1 vs 3.
Answer: A

Approach: Counting squares — straight and tilted, by size.
Solution:
Central square (ABCD) is cut by a vertical and a horizontal midline, by a tilted square (diamond) joining the side midpoints, and by short diagonals inside the diamond. Four tilted rectangles/squares stick out at the corners, each split lengthwise in half.
Small tilted squares inside the diamond (around the centre): 4
Quarter squares of the central square: 4
Tilted corner squares (the four arms): 4
Larger tilted squares made of an arm's inner half + the adjoining part of the diamond: 4
The diamond (square on the side midpoints): 1
Central square ABCD: 1
Total = 4 + 4 + 4 + 4 + 1 + 1 = 18.
Cetking shortcut: Tilted squares are easy to miss — count straight ones first, then tilted ones by size.
Answer: C

Approach: Minimum colours — map colouring of concentric rings.
Solution:
Outer ring: 8 segments in a cycle — an even cycle needs only 2 colours, alternating (1, 2, 1, 2 …).
Next ring (undivided): touches every outer segment ⇒ colour 3.
Next ring: 6 segments (even cycle) touching ring 3 ⇒ alternate colours 1 and 2.
Next ring (undivided): touches all 6 segments ⇒ colour 3.
Centre circle: touches only colour 3 ⇒ colour 1.
Minimum = 3 (two alternating colours for the segments + one for the solid rings).
Why the other options are wrong:
4, 5, 6, 7: more than needed — an even number of segments in each ring lets two colours alternate.
Cetking shortcut: A ring with an EVEN number of segments needs 2 colours; an ODD number would need 3. Solid rings in between take one extra colour.
Answer: A

Answer: B ✓ official key
Approach: Minimum straight lines — extend every collinear piece into one line.
Solution:
Treat the two squares as 2 × 1 units, with roofs on top and V-shapes below.
Horizontal lines: top edge, bottom edge = 2.
Vertical lines: left, middle, right = 3.
Slanting '/' lines: left-square diagonal continuing into the right roof; right-square diagonal continuing down into the left V; left roof's left edge; right V's right edge = 4.
Slanting '\' lines: left-square diagonal continuing down into the right V; right-square diagonal continuing up into the left roof; right roof's right edge; left V's left edge = 4.
Total = 2 + 3 + 4 + 4 = 13.
Why the other options are wrong:
11: undercounts — the outer roof and V edges are separate lines. 15, 21, 50: count one straight line in several pieces.
Cetking shortcut: Before counting, extend each diagonal — here every square diagonal continues into a roof or V edge.
