The ratio of the present age of a mother to that of her daughter is 7...
Let the mother's age be 7x and the daughter's age be x.
Four years ago,
(7x – 4)/(x – 4) = 19/1
Or, 7x – 4 = 19x – 76
72 = 12x
6 = x
The mother's age four years from now will be 7x + 4 = 46 years.

The ratio of the present age of a mother to that of her daughter is 7...
Given Information:
- Ratio of mother's age to daughter's age presently: 7 : 1
- Ratio of their ages four years ago: 19 : 1
Solution:
Step 1: Assign Variables
Let the present age of the mother be 7x and the present age of the daughter be x.
Step 2: Calculate their ages four years ago
Four years ago, the mother's age would have been 7x - 4 and the daughter's age would have been x - 4.
Step 3: Set up the equation
According to the given information, the ratio of their ages four years ago was 19 : 1:
(7x - 4) / (x - 4) = 19 / 1
Solving this equation, we get x = 5.
Step 4: Find the mother's current age
Mother's present age = 7x = 7 * 5 = 35 years
Step 5: Calculate the mother's age four years from now
Mother's age four years from now = 35 + 4 = 39 years
Therefore, the mother's age four years from now will be 39 years. Hence, the correct answer is option C) 46 years.
