Answer 1

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.
