Question 114

What is the average number of boys in schools P and Q together ?

Solution

Total number of students in P = 2500

Percentage of girls = 40%

So, the number of boys = .60 * 2500 = 1500

Total number of students in Q = 3000

Percentage of girls = 45%

So, the number of boys = .55 * 3000 = 1650

So, the average = (1500 + 1650)/2 = 1575
