Five years ago, the average age of P, Q and R was 25 years and seven years ago, the average age of Q and R was 20 years. The present age of P is
-
- 36 years
- 29 years
- 24 years
- 21 years
- 36 years
Correct Option: A
As per the given details in question, we have
Sum of the present age of P, Q and R = (25 × 3 + 3 × 5) years
Sum of the present age of P, Q and R = (75 + 15) years = 90 years
Sum of the present age of Q and R = (20 × 2 + 2 × 7) years
Sum of the present age of Q and R = 54 years
∴ p’s present age = Sum of the present age of P, Q and R - Sum of the present age of Q and R
Hence , p’s present age = (90 – 54) years = 36 years
