Answer 1

This is the answer and you can copy the exact thing your notebook. I had actually typed it out but they said I had abusive words, whereas my only intention is to help others.

Your Welcome :)

Answer 2

Let the boy and girls be 5x and 3x

Boy are 20 more than girls

therefore,

5x= 3x+20

2x=20

x=10

then we substitute

if x is 10 then girls = 3×10=30

boys= 5 x 10= 50

so boys and girls = 50 and 30
