Question

In a school 5 by 8 are girls and girls are 120 more than boys so what is the total strength of school and how many boys are there

Answer 1

Step-by-step explanation:

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)
