Study the graphs carefully to answer the question that follow:
Total number of children in 6 different schools and the percentage of girls in them
Percentage of Girls
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
