Question

In a school, 5/8 of total students are girls. If the number of girls is 120 more than that of the boys, what is the strength of the school? How many boys are there?
Please give answer of my question..​

Answer 1

Let the no. of students be x

no. of girls= 5x/8....(1)

no.of boys= 3x/8.... (2)

5x/8= 120+ 3x/8

5x/8-3x/8= 120

2x/8= 120

2x= 120*8

2x= 960

x=960/2

x=480

Putting the value of x in1:

5x/8= 5(480)/4= 300 (no. of girls)

Putting the value of x in 2

3x/8= 3(480)/8= 180 (no. of boys)

Hope it helps.

Answer 2

Step-by-step explanation:

let the total no. of student = x

no. of girls = 5/8

no. of boys = x - 5/8x

= 3/8x

according to question

= 5/8x - 3/8x = 120

=2/8x = 120

= x = 120×8/2

= x =480

no. of boys =3/8x

3/8×480 = 180

no. of girls = 5/8x

=5/8×480 = 300
