Answer 2

Answer: 400 Boys

Explanation:

Given,

Fraction of boys = 5/8

No. of Girls in class = 240

To find,

Total no. of Boys = ?

Let the number of Boys is X

                    Fraction of girls = 1 - 5/8 = 3/8

So, girls = 3/8 × x

It means, Faction of Girls = 3/8

240 = 3/8 × x

x = 240 × 8 /3 = 640

                   Number of boys = 5/8 of 640

= 5/8 × 640

= 400

Therefore, Total no. of boys in a school are 400.
