What is the average number of boys studying in schools A and C?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 680.
Given that
Total number of boys = 2000
The number of boys studying in schools A = 2000 × 13/100 = 260
The number of boys studying in schools C = 2000 × 55/100 = 1100
Hence, the average number of boys studying in schools A and C = (260 + 1100)/2 = 1360/2 = 680
