Question

Answer 1

Answer:

Step-by-step explanation:

Solution:-

Let the present age of the son be 'x' years.

Then father's age will be (x + 30) years

Given : After 12 years, the father will be three times as old as his son. Therefore,  

(x + 12)3 = x + 30 + 12

3x + 36 = x + 42

3x - x = 42 - 36

2x = 6

x = 3  

The present age of son is 3 years and the present age of the father is 3 + 30 = 33 years.
