Which section has the maximum pass percentage in at least one of the two examinations?
A Section
B Section
C Section
D Section
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 % = 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.

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.
