Solution

Let's solve this step by step:

  1. Let's assume the present age of A is 3x and the present age of B is x.

  2. According to the problem, four years ago, the ratio of their ages was 4:1. So, we can write this as (3x - 4) / (x - 4) = 4/1.

  3. Solving this equation, we get x = 8.

  4. Therefore, the present age of A is 3x = 3*8 = 24.

However, 24 is not an option in the given choices. It seems there might be a mistake in the problem or the options provided.
