    Solution

    ATQ,

    Let the present age of ‘B’ be 7x years. So, the present age of ‘A’ = (4/7) × 7x = 4x years The present age of ‘C’ = (2/3) × 7x = (14x/3) years According to the given information: 7x - 4x = 18 ⇒ x = 6 So, present age of ‘C’ = (14/3) × 6 = 28 years Age of ‘C’ five years ago = 28 - 5 = 23 years
