Ratio of boys and girls in class = 7:5
let no of boys be 7x
no of girls be 5x
then total number of students = 7x+5x = 12x
The number of boys is 8 more than number of girls
so, 7x = 5x + 8
7x - 5x = 8
2x = 8
x = 4
no of boys = 7x = 7(4)= 28
no of girls = 5x = 5(4)= 20
total number of students =12x=12(4)=48
