From a class of 24 boys, a boy, aged 10 years, leaves the class and in his place a new boy is admitted. As a result, the average age of the class is increased by 2 months. What is the age of the new boy ?
-
- 12 years
- 15 years
- 14 years
- 13 years
- 12 years
Correct Option: C
Here , Age of replaced boy = 10 years
Total age increase = 2 × 24 = 48 months = 4 years
∴ Age of the new boy = Age of replaced boy + Total age increase
Hence , Age of the new boy = 10 + 4 = 14 years.
