The sum of the present ages of a mother and her daughter is 50 years. Five years ago, the mother's age was 7 times her daughter's age. Then Mother's age 5 years hence will be ?

Five years ago, the sum of their ages was 40 years (50 minus 2 times 5). Let the daughter's age at that time be y, which makes the mother's age 7y; the equation becomes y plus 7y equals 40, so y equals 5. The mother's age five years ago was 35, meaning her present age is 40, and her age five years hence will be 45.
