Answer 2

☞ The numbers of boys and girls are in ratio 5 : 4.

Let number of boys be 5M and number of girls be 4N.

☞ Number of boys (5M) is (equal to) 9 more than (plus) number of girls (4M).

• A.T.Q.

=> 5M = 9 + 4M

=> 5M - 4M = 9

=> M = 9

Number of Boys = 5M = 5 × 9 = 45

And

Number of Girls = 4M = 4 × 5 = 20
