Solution

Let's solve this step by step:

Step 1: Let's assume the present age of the mother is 7x and the present age of the daughter is x.

Step 2: According to the problem, four years ago the ratio of their ages was 19:1. So, we can write this as (7x - 4) / (x - 4) = 19/1.

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

Step 4: Substituting x = 8 in the equation of the mother's age, we get 7x = 7*8 = 56 years.

Step 5: The question asks for the mother's age four years from now. So, we add 4 to 56 to get 60 years.

However, 60 years is not an option in the given choices. There seems to be a mistake in the problem or the options provided.
