then rohan's present age =( x+9) years

10 years ago raju's age =( x-10) years

In 10 years rohan's age = x+9+10 = x+19

But as per sum:

x+19 = 2(x-10)

x+19 = 2x-20

2x-x = 20+19

x = 39

Therefore present age of raju = 39 years

present age of rohan = 48 years

Then,

Now,

After 10 years,

But according to Question,

Therefore,

⇒

⇒2x-20=x+19
