    Solution

    Let, income and expenditure of β€˜P’ be Rs. β€˜5x’ and β€˜2x’, respectively And, income and expenditure of β€˜Q’ be Rs. β€˜5y’ and Rs. β€˜3y’, respectively. ATQ, 5x – 2x = 1500 Or, 3x = 1500 Or, x = 1500/3 = 500 Also, 5x + 5y = 5500 Or, x + y = 1100 So, y = 1100 – 500 = 600 Therefore, expenditure of β€˜Q’ = 3 Γ— 600 = Rs. 1,800
