Answer 2

Hello Dear.

Here is the answer---

Let the Present age of the Son be x years.

Thus, Present age of the Aman  = 3 × son's  Age
                                                       = 3x 


Before 10 years,
Aman's age = (3x - 10)years.

Son's age = (x - 10) years.

According to the Question,

  Aman's age 10 years ago = 5 × Son's age 10 years ago.
      5(x - 10) = 3x - 10
       5x - 50 = 3x - 10
  ⇒ 5x - 3x = 50 - 10
  ⇒ 2x = 40
       x = 20 years.

Present age of Son = x years
                                = 20 years.

Thus, Present age of the Aman = 3x years.
                                                  = 3 × 20 years.
                                                  = 60 years.
