boys = 7x

girls = 5x

7x = 5 x + 8

2x = 8

x = 4

boys = 7x = 7×4 = 28

girls = 5×4 = 20

Total students = 28 + 20 = 48

Answer 2

HI FRIEND...

HERE IS YOUR ANSWER⤵

No. of boys = 7x
No. of girls = 5x+(8)

A/Q

5(x+8) = 7x
5x+40 = 7x
5x- 7x = 40
-2x = 40

x = 40÷2 = 20

Hence, the no. of girls = 20
And the no. of boys = 20+8 = 28

Therefore, the total strenght of class = 20+28 = 48
