Question

2.A father is 30 years older than his son . in 12 years .the man will be three times as old as his son . find their present age .

Answer 1

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.
