Description: The average number of girls in schools D and E is approximately what per cent less than the number of students in school C?

Solution

Total number of students in D and E = $$\frac{105\ +\ 54}{360}\times\ 5400\ =\ 2385$$.
Total number of girls in D and E = 2385 - (450+1017) = 918.
The average number of girls in schools D and E = 918/2 = 459.
Number of students in C = $$\frac{64}{360}\times\ 5400\ =\ 960$$.
The required percentage = $$\frac{960-459}{960}\times\ 100\ \approx\ 52.2\%$$.
