i HOPE this helps you.

Let the PRESENT AGE of deepak=5x

Let the present age of Rishi=6x

twelve years now age of deepak=5x-12

twelve years now age of Rishi= 6x-12

according to question

5x-6/6x-12=9/10

cross multiple

50x+120=54xX108

54x-50x=120-108

4x=12

x=3

present age of deepak=5x=5×3=15 years

present age of Rishi=6x=6×3=18 YEAR
