Ratio of girls to boys = 6:2
Let girls = 6x and boys = 2x
total = 6x+2x = 8x
given that total = 80
⇒ 8x = 80
⇒ x = 80/8
⇒ x = 10
girls = 6x = 6×10 = 60
Let girls = 6x and boys = 2x
total = 6x+2x = 8x
given that total = 80
⇒ 8x = 80
⇒ x = 80/8
⇒ x = 10
girls = 6x = 6×10 = 60

total students= 80
ratio of boys and girls= 6:2
let the common multiple be x
6x + 2x=80
8x=80
x=80÷8
x=10
now substitute x value in 6x and 2x
no. of girls= 6x
= 6(10)
= 60
no. of boys= 2x
= 2(10)
= 20
ANS= No of girls are 60
