Data Analysis (DA) for SBI PO Practice Paper

(A). In an examination (consisting of two papers Physics and Chemistry) total 300 students appeared. Out of that the ratio of boys to girls is 3 : 2. The number of boys who passed only in Physics is 25% of the total number of boys and this number is 3/2 of the number of girls who passed only in Chemistry. The number of girls who passed in both the papers is 13 1/3 % of the total 3 number of students and the number of boys who passed in both the papers is 180% of the number of girls who passed in both the papers. None of the candidate failed in both the papers.

Answers:-

(A). 1. 4
2. 1; Reqd %= 100 21%
3. 5; Total students who passed in Physics = 45 + 50 + 40 +72 = 207
4. 3;
5. 4; Students who passed at most in one subject = 45 + 50 +30 + 63 = 188

(B).

6. 2; Reqd % = 45/250× 100 = 18%
7. 4
8. 4; WC 1979 = 150
Only WC 1983 = 50
Reqd number times = 150/50= 3
9. 2; Only WC 1979 = 54
Only WC 1975 = 45
Reqd % = 54/45× 100 = 120%
10. 3; WC 1975 and WC 1979 = 36
WC 1979 and WC 1983 = 48
WC 1975 and WC 1983 = 5
Total = 36 + 48 + 5 = 89
Reqd % = 89/250× 100 = 35.6%
