Question 142

The ratio of the present ages of a mother and daughter is 7:1 Four years ago the ratio of their ages was 19:1 what will be the mother’s age four years from now ?

Solution

Let the present ages of daughter and mother be d and m respectively.

7d = m

19(d-4) = m-4

=> 19d - 76 = 7d - 4

=> 12d = 72

=> d = 6 and m = 42

Mother's age four years from now will be 42 + 4 = 46
