Question

In the class of 40 pupils the number of girls is three fifths of the number of boys.find the number of boys in the class​

Answer 1

Total no. of students= 40

Total no. of girls= 3/5*40

=24

Total no. of boys= 40-24

=16

Answer 2

Answer:

Let no.of boys be x

Then, the no.of girls = 3/5x

x + 3/5x = 40

8/5x = 40

x = 40 ÷ 8/5

x = 40 × 5/8

x= 5×5 = 25

No of boys = 25

and no.of girls = 25 × 3/5

= 5×3 = 15
