Question
Present ages of 'A' and 'B' are in the ratio 3:2,
respectively. Present age of 'C' is 90% more than 'B'. If the difference between present ages of 'C' and 'A' is 8 years, then find the present age of 'B'.Solution
Let the present age of 'A' be '3x' years So, present age of 'B' = 3x × (2/3) = '2x' years So, present age of 'C' = 2x × 1.9 = '3.8x' years ATQ; 3.8x - 3x = 8 Or, 0.8x = 8 So, x = 10 So, present age of 'B' = 2x = 10 × 2 = 20 years
