Question

In a school 5\8 of the total students are girls.if the number of girls is 120 more than that of boys,what is the strength of the school?How many boys are there?

Answer 1

Hi ,

Let the total students = x

Number of girls = 5x / 8

Number of boys = ( x - 5x / 8 ) = 2x/8


According to the problem given,

Number of girls - number of boys =

120

5x / 8 - 2x / 8 = 120

( 5x - 2x ) /8 = 120

3x / 8 = 120

x = 120 × ( 8 / 3 )

x = 40 × 8

x = 320

Therefore ,

Total students = x = 320

Number of boys = 2x / 8

= ( 2 × 320 ) / 8

= 2 × 40

= 80

I hope this helps you.
