Question
The current ages of Raman and Raghav are in the ratio of
5:4. In six years, their ages will have a ratio of 11:9. What was the ratio of their ages ten years ago?Solution
Let present age of Raman and Raghav be 5x and 4x years, respectively. According to question, (5x + 6) / (4x + 6) = 11/9 45x + 54 = 44x + 66 x = 12 Raman’s present age = 5x = 5×12 = 60 years Raghav’s present age = 4x = 4×12 = 48 years Required ratio = (60 – 10) : (48 - 10) = 50:38 = 25:19
