## The number of boys and girls are in the ratio of 7:5 . The number of boys is 8 more than girls.Find the number of boys and girls ?

answer - Let the common multiples of boys and girls be 7x and 5x

number of girls = 5x

number of boys = 7x + 8

according to condition

7x - 5x = 8

2x = 8

x = 8/2

x = 4

number of boys = 7 X x = 7 X 4 = 28

number of girls = 5 X x = 5 X 4 = 20

-------> number of boys is 28 and number of girls is 20
