Question

If the average age of A, B and C is 22 years and the average age of B and C is 25 years, then find A's age after 9 years.
1. 35 years
2. 50 years
3. 45 years
4. 25 years

Answer 1

Correct Answer - Option 4 : 25 years

Given:

Average age of A, B and C = 22 years

Average age of B and C = 25 years

Calculation:

Total age of A, B and C = 22 × 3 = 66 years

Total age of B and C = 25 × 2 = 50 years

A's present age = 66 - 50 = 16 years

∴ A's age after 9 years = 16 + 9 = 25 years
