Question

Answer it fast...................​

Answer 1

Let the no. of girls be 5x

No. of boys=7x

According to the question

5x+8=7x

7x-5x=8

2x=8

x=8/2

x=4

No. of girls=5*4=20

no. of boys=7*4 or 5*4+8=28

Hence the total strength of the class is 20+28=48

Answer 2

Let the boys and girls in a class be 7xanf and 5x

No. of boys= No.of girls +8

7x-5x=8

x=4

Total strength= 7x+5x=48

therefore total strength of the class is 48.....
