The present age of a father is three times the age of his son. Five years ago, father's age was four times the age of the son. What is the present age of son?
-
- 20 years
- 18 years
- 15 years
- 12 years
Correct Option: C
Let us assume that present age of son is P years then his father's present age will be 3P.
According to question,
Five years ago, father's age was four times the age of the son.
Then
4 (P - 5) = 3P - 5
⇒ 4P - 20 = 3P - 5
∴ P = 15 years
The present age of Son is 15 Years.
