Question 115
What is the respective ratio of the number of girls in school P to the number of girls in school Q ?
Solution
Total number of students in P = 2500
Percentage of girls = 40%
So, the number of girls = .40 * 2500 = 1000
Total number of students in Q = 3000
Percentage of girls = 45%
So, the number of girls = .45 * 3000 = 1350
So, the ratio = 1000 : 1350 = 100 : 135 = 20 : 27
