Question
The ratio of the present ages of father and his son is
5:2. The product of their ages 4 years ago was 31 times of his son’s age that year. What was son’s age 2 year ago?Solution
Let present age of father and son be 5x and 2x respectively. According to question, => (5x – 4) (2x – 4) = 31 × (2x – 4) => (5x – 4) = 31 => 5x = 35 => x = 7 Therefore, son’s age 2 years ago = (2x – 2) = 12 years
