Question
The ratio of the present ages of P and Q is 7:4. After 8
years, the ratio of their ages will be 9:6. Find the ratio of their ages 4 years ago.Solution
Let the present ages of P and Q be 7x and 4x years, respectively
(7x + 8) / (4x + 8) = 9 / 6
Or, 42x + 48 = 36x + 72
Or, 6x = 24
Or, x = 4
Required ratio = (7x – 4) / (4x – 4) = (28 – 4) : (16 – 4) = 24 : 12 = 2 : 1
