Question

Rozy is 5 year younger than her brother.after 4 year,there age will be in ratio 2:3 find there present age.

Answer 1

Step-by-step explanation:

Let the present age of Rozy be 'x' and that of his brother be 'y'

y - x = 5

i.e. y = 5 + x

After 4 years..............

x+4/y+4 = ⅔

3(x + 4)= 2(y + 4)

3x + 12 = 2y + 8

3x + 12 = 2(x + 5) + 8

3x + 12 = 2x + 10 + 8

3x - 2x = 18 - 12

x = 6

y = 6 + 5 = 11

Rozy's present age = 6

Brother's present age = 11
