Solution

Let's solve this step by step:

  1. The present age ratio of A and B is 8:9. Let's assume the present age of A is 8x and the present age of B is 9x.

  2. After 9 years, the ratio of their ages will be 19:21. So, we can write the equation as (8x + 9) / (9x + 9) = 19/21.

  3. Solving this equation, we get x = 3.

  4. So, the present age of B is 9x = 9*3 = 27 years.

  5. C is 3 years younger than B. So, the present age of C is 27 - 3 = 24 years.

So, the correct answer is 24 years.
