Question

the number of boys and girls are in the ratio 7:5 the number of boys are more than the number of girls. what is total class strength​

Answer 1

let the no. of boys be - 7x

and the no. of girls be -5x

according to the question

7x–5x=8

2x=8

x=8/2=4

therefore no. of boys =7*4=28

and no. of girls =5*4=20

total class strength =28+20=48
