Let the present age of son be x
And the present age of father be 3x
As given in the question,
The age of son after 12 years = x + 12
And the age of father after 12 years = 2(x+12)
3x + 12 = 2 (x + 12)
= 3x + 12 = 2x + 24
= x = 12
The present age of the son is 12 years
The present age of the father is (12 * 3) 36 years.
