Answer:

Let the age of Sonu and Monu be 3x and 2x respectively.

After 5 years -

Sonu's age = 3x + 5

Monu's age = 2x + 5

Now,

 \frac{3x + 5}{2x + 5}  =  \frac{5}{3}  \\  \\ 5(2x + 5) = 3(3x + 5) \\  \\ 10x + 25 = 9x + 15 \\  \\ 10x - 9x = 15 - 25 \\  \\ x =  - 10

Since, age can't be negative, question is wrong.
