Three-fourth of the number of girls in a school is equal to half of the number of boys. If the school has 1420 pupils, how many of them are boys?

Explanation

Let's say the number of girls is G and the number of boys is B.

3/4G = 1/2B

Given that the total number of pupils is 1420:

G + B = 1420

Solving the equations, we get B = 852.

The correct answer is 852.
