Question 111

What is the total percentage of boys in schools R and U together (rounded off to two digits after decimal)

Solution

Total number of students in R = 2000

Percentage of girls = 28%

So, the number of boys = .72 * 2000 = 1440

Total number of students in U = 1000

Percentage of girls = 15%

So, the number of boys = .85 * 1000 = 850

So, the percentage of boys = $$ \frac{850+1440}{2000+1000}$$* 100

= 76.33%
