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

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		%
		(28 + 14 + 6 + 64)					112

= 75%.

For Section B

		(12 + 17 + 55)	x 100		% =		84	x 100		%
		(23 + 12 + 17 + 55)					107

= 78.5%.

For Section C

		(8 + 9 + 46)	x 100		% =		63	x 100		%
		(17 + 8 + 9 + 46)					80

= 78.75%.

For Section D

		(13 + 15 + 76)	x 100		% =		104	x 100		%
		(27 + 13 + 15 + 76)					131

= 79.39%

Clearly, the pass percentage is maximum for Section D.
