Which section has the maximum pass percentage in at least one of the two examinations?
Answer: Option
Explanation:
Pass percentages in at least one of the two examinations for different sections are:
| For Section A |  |
(14 + 6 + 64) | x 100 | ![]](/_files/images/data-interpretation/common/15-sym-cbracket-h1.gif) |
% = | |
84 | x 100 | |
% = 75%. |
| (28 + 14 + 6 + 64) | 112 |
| For Section B | |
(12 + 17 + 55) | x 100 | |
% = | |
84 | x 100 | |
% = 78.5%. |
| (23 + 12 + 17 + 55) | 107 |
| For Section C | |
(8 + 9 + 46) | x 100 | |
% = | |
63 | x 100 | |
% = 78.75%. |
| (17 + 8 + 9 + 46) | 80 |
| For Section D | |
(13 + 15 + 76) | x 100 | |
% = | |
104 | x 100 | |
% = 79.39%. |
| (27 + 13 + 15 + 76) | 131 |
Clearly, the pass percentage is maximum for Section D.

Just we see, what is the pass percentage more in all sections here 76 is more than 64 55 46 so I think that 76 is the right answer.

I think, we can get answer through average also like:
A: 14+6+64/3 = 28.
B: 12+17+55/3 = 28.
C: 8+9+46/3 = 21.
D: 13+15+76/3 = 34.66.
Max value for D and answer is also D.
A: 14+6+64/3 = 28.
B: 12+17+55/3 = 28.
C: 8+9+46/3 = 21.
D: 13+15+76/3 = 34.66.
Max value for D and answer is also D.

If we just add marks of passed student then d's sum is greater than a b and c then its not needed to calculate percentage.
