multiply both sides of the ratio with 4. You will get 28:20. Since the number of boys is 8 more than the girls, the required answer is 28+20 = 48

___________
Let the no. of girls be 5x
&
No. of boys=7x
Now
==> 5x+8=7x
==>7x-5x=8
==> 2x=8
==> x=8/2
==> x=4
Number of girls=5× 4=20
no. of boys=7*4 or 5×4+8=28
Thus
the total strength of the class
==> 20+28=48
