    Solution

    ATQ,

    Let present age of 'Q' be ‘x’ years Present age of 'P' = 1.20 × x = ‘1.2x’ years Present age of 'R' = (1.2x – 6.5) years Present age of 'S' = (1.2x – 6.5 + 9) = (1.2x + 2.5) years ATQ, x + 1.2x + 1.2x – 6.5 + 1.2x + 2.5 = 22 × 4 = 88 4.6x = 92 x = 20 Present age of 'S' = 1.2 × 20 + 2.5 = 26.5 years
