-
- 12 years
- 11 years
- 10.5 years
- 10 years
- 12 years
Correct Option: B
Here , The average age of a father and a mother = 35 years
Total age of ( Father + mother ) = 2 × 35 = 70 years
The average age of father , mother and son = 27 years
Total age of ( Father + mother + son ) = 27 × 3 = 81 years
∴ Son’s age = 81 – 70 = 11 years
