DI Logic based Data Interpretation

CAT and some of the other exams have evolved from traditional Calculation based DI to into more logic based questions like the graph below.

Sample question.
The Dean office recently scanned student results into the central computer system. When their character reading software cannot read something, it leaves the space blank. The scanner output read as follows:

In the grading system, A, B, C, D, and F grades fetch 6, 4, 3, 2, and 0 grade points respectively. The Grade Point Average (GPA) is the arithmetic mean of the grade points obtained in the five subjects. For example Nisha GPA is (6 + 2 + 4 + 6 + 0) / 5 = 3.6. Some additional facts are also known about the students grades. These are
(a) Vipul obtained the same grade in Marketing as Aparna obtained in Finance and Strategy.
(b) Fazal obtained the same grade in Strategy as Utkarsh did in Marketing.

Q1. What grade did Preeti obtain in Statistics?
1. A
2. B
3. C
4. D

1. Ismet
2. Hari
3. Jagdeep
4. Manab

Q3. In Strategy, Gowri grade point was higher than that obtained by
1. Fazal
2. Hari
3. Nisha
4. Rahul

Q4. What grade did Utkarsh obtain in Finance?
1. B
2. C
3. D
4. F

1 ANS: GPA of Preeti = 3.2
=> (F+D+x+D+y)/5 = 3.2
=> x + y = 12
So only combination possible is A, A.
So Preeti obtained A grade in statistics.

2 ANS: (4) Tara received same grade in 3 courses. We already know that Tara has got B grade in one of the subject and GPA is 2.4. So in 3 courses in which he scored same grade is B. So Tara has received the same grade as Manab.

3 ANS: GPA of Gowri is 3.8
=>3 + 3 + 6 + x + 4 = 3.8 Ã— 5
=>16 + x = 18
=>x = 2
So in strategy, Gowri’s grade is C.
Rahul’s grade in strategy = (4.2 Ã— 5) â€“ 15 = 6, i.e., A.
Fazal’s grade in strategy = (2.4 Ã— 5) â€“ 8 = 4, i.e., B.
Hence, Gowri’s grade will be higher than that of Hari.

4 ANS: Fazal GPA = 2.4
=> D + F + B + P + D = 2.4 Ã— 5
2 + 0 + 4 + P + 2 = 12
P = 4
So his grade in strategy is B.
So Grade of Utkarsh in marketing is also B.
So for Utkarsh, x + B + F + C + A = 3 Ã— 5
x + 4 + 0 + 3 + 6 = 15
x = 2
So grade of Utkarsh in finance = D.
