The sum of the ages of a mother and a daughter is 50 years. Also, 5 years ago, the mother's age was 7 times of the age of her daughter. The present ages of the mother and the daughter respectively are ?
-
- 35 years, 15 years
- 38 years, 12 years
- 40 years, 10 years
- 42 years, 8 years
Correct Option: C
Let the daughter's present be x years.
Then, mother's present age = (50 - x) years
Now, 7(x -5) = (50 - x - 5)
⇒ x = 10
So, the present ages of mother and daughter are 40 years and 10 years respectively.
