Direction (1-5) : Directions: Study the following graph carefully & answer the questions given below it.
Production of Steel (in lakh tonnes) by different companies
for three consecutive years 2000, 2001, 2002
Q1) Minimum production and maximum production of how many companies is in the ratio 2 : 3?
A.1
B.2
C.3
D. Can’t be determined
E. None of these
Explanation
Correct Option: B
The ratio of minimum production to maximum production in different companies are as follows:
Comp. Min Max Ratio
A → 40 : 60 ⇒ 2 : 3
B → 40 : 70 ⇒ 4 : 7
C → 30 : 40 ⇒ 6 : 7
D → 40 : 80 ⇒ 4 : 7
E → 50 : 90 ⇒ 8 : 9
F → 30 : 45 ⇒ 2 : 3
Only twice minimum production and maximum production have the ratio of 2 : 3.
Hence, option B is correct.
Q2) What is the difference of average production of 2001 & 2002 in lakh tonnes?
A.2
B.3.3
C.4.5
D.5
E .None of these
Explanation
Correct Option: B
Average production in the year 2001 –
⇒ 60 + 60 + 40 + 80 + 50 + 40
6
⇒ 330 ⇒ 55.
6
Average production in the year 2002 –
⇒ 40 + 70 + 35 + 70 + 90 + 45
6
⇒ 350 ⇒ 58.3
6
Difference ⇒ 58.3 – 55 = 3.3.
Hence, option B is correct.
Q3) Total production of A type company is what percentage of total production of E type company?
A.66.5
B.67.3
C.68.18
D.70.4
E. None of these
Explanation
Correct Option: C
Total production of A type company –
⇒ 50 + 60 + 40 ⇒ 150
Total production of E type company –
⇒ 80 + 50 + 90 ⇒ 220
According to question
150 × 100 ⇒ 750 ⇒ 68.18
220 11
Hence, option C is correct.
Q4) Average production of A, D & E is approximately how much percentage of average production of B, C & F ?
A.121%
B.144%
C.134%
D.164.3%
E. None of these
Explanation
Correct Option: B
Average production of A, D & E
150 + 190 + 220 ⇒ 560
3 3
Average production of B, C & F
170 + 105 + 115 ⇒ 390 ⇒ 130
3 3
According to question –
(560/3) × 100
130
⇒ 56000
390
⇒ 143.58% ≈ 144%
Hence, option B is correct.
Q5) What is the approximate average of three highest productive (who has maximum production) companies in lakh tonnes?
A.125
B.165
C.185
D.193
E. None of these
Explanation
Correct Option: D
Total production –
A → 150
B → 170
C → 105
D → 190
E → 220
F → 115
Average of three highest production which is clearly of company B, D and E
= 170 + 190 + 220
3
= 193.34 ⇒ 193 lakh tonnes
Hence, option D is correct.
