Given:
- Four years ago, the sum of the ages of mother and her two daughters was x years
To find: The sum of the ages after two years.
Solution:
- Four years ago, the sum was x years.
- So the present sum of their age is
- = x + 3 * 4 years
- = x + 12 years.
- Thus after 2 years, the sum of the ages will be
- = (x + 12) + 2 * 3 years
- = x + 12 + 6 years
- = x + 18 years
Answer: the sum of the ages after 2 years will be x + 18 years.
