Which section has the maximum pass percentage in at least one of the two examinations?

[A]. A Section
[B]. B Section
[C]. C Section
[D]. D Section

Answer: Option D

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.

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.

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.

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.
