A school has four sections A, B, C, D of Class IX students.
The results of half yearly and annual examinations are shown in the table given below.
Which section has the maximum pass percentage in at least one of the two examinations?
Section A
Section B
Section C
Section D
Correct answer is D
Pass percentages in at least one of the two examinations for different sections are:
For Section A [ (14 + 6 + 64)/(28 + 14 + 6 + 64) x 100 ] % = [ 84/112 x 100 ] % = 75%
For Section B [ (12 + 17 + 55)/(23 + 12 + 17 + 55) x 100 ] % = [ 84/107 x 100 ] % = 78.5%
For Section C [ (8 + 9 + 46)/(17 + 8 + 9 + 46) x 100 ] % = [ 63/80 x 100 ] % = 78.75%
For Section D [ (13 + 15 + 76)/(27 + 13 + 15 + 76) x 100 ] % = [ 104/131 x 100 ] % = 79.39%
Clearly, the pass percentage is maximum for Section D.
