3.

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

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.

 Lucky said: (Jan 5, 2016) 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.
