Question
Present ages of 'A' and 'B' are in the ratio 7:5,
respectively. Present age of 'C' is 60% more than 'B'. If the difference between present ages of 'C' and 'A' is 9 years, then find the present age of 'B'.Solution
Let the present age of 'A' be '7x' years So, present age of 'B' = 7x × (5/7) = '5x' years So, present age of 'C' = 5x × 1.6 = '8x' years ATQ; 8x - 7x = 9 Or, x = 9 So, present age of 'B' = 5x = 9 × 5 = 45 years
