Question
Currently, the age of 'A' is 37.5% greater than 'B's
age, with a difference of 15 years between them. In five years, what will be the age ratio of 'A' to 'B'?Solution
Let present age of ‘B’ be ‘8x’ years. So, present age of ‘A’ = 8x × 1.375 = ‘11x’ years ATQ; 11x – 8x = 15 Or, 3x = 15 So, x = 5 5 years hence from now, Age of ‘A’ = 11x + 5 = 55 + 5 = 60 years Age of “b’ = 8x + 5 = 40 + 5 = 45 years Required ratio = 60:45 = 4:3
