    Solution

    ATQ,

    Let the present age of 'P' and 'Q' be 'x' and 'y' years respectively. ATQ: x + 5 = y - 4 Or, y - x = 9 ---------- (I) And, 2x = y + 3 Or, 'y' = 2x - 3 On putting value of 'y' in equation (I) , We get, 2x - 3 - x = 9 Or, 'x' = 12 Therefore, required age = 12 - 4 = 8 years
