ANS:D - D Section

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.
