-
- 24
- 4
- 40
- 14
Correct Option: B
Given :- The average age of father and his son = 22 years.
Total age of father and his son = 2 x 22 = 44 years.
The ratio of age of father and his son = 10 : 1
Suppose the age of son is P years
Therefore, age of father = 10P years
According to question,
| = 22 | 2 |
⇒ 11P = 44
| ∴ P = | = 4 years | 11 |
Age of father = 4P = 10 x 4 = 40 years
