Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 146.15 percent.
The average number of boys in S1 and S2 = 12000/100 × (31 + 7)/2 = 2280
The average number of boys in S6 and S8 = 12000/100 × (11 + 15)/2 = 1560
Required percentage = 2280/1560 × 100 = 146.15%
