Ravi has spent a quarter (1/4) of his life as a boy , one fifth (1/5) as a youth , one third (1/3) as a man and thirteen (13) years in old age . What is his present age ?
-
- 70 years
- 80 years
- 60 years
- 36 years
Correct Option: C
Suppose that the Ravi present age is A years.
According to the given question,
A/4 + A/5 + A/3 + 13 = A
⇒ (15A + 12A + 20A)/60 = A - 13
⇒ 47A = 60A - 780
⇒60A - 47A = 780
⇒13A = 780
∴ A = 780/13 = 60 years
