Question

Please Answer with steps

Answer 1

let no of boys be 7x
let no of girls be 5x

A.T.Q.= 7x = 5x +8
=7x -5x =8
= 2x= 8
= X=8/2
=X=4

therefore, no of boys =7(4)= 28
no of girls = 5(4)= 20

total class strength= no of boys + no of girls
= 28+ 20= 48

$\huge\underline{\purple{\bold{Given}}}$
Number of boys and girl in class are in ratio 7:5

Let,
Ratio be x
boys ratio=7x
girl ratio =5x
A/q
=>5x+8=7x
=>8=7x-5x
=>8=2x
=>4=x

Number of boys=>7x=7×4=28 boys•
Number of girls=>5X=5×4=20 girls•

so,
➡The class strength= number of boys+number of girls
➡ 28+20=48

I hope it helps you
