    C Rs. 1,500 Correct Answer Incorrect Answer
    D Rs. 1,800 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let, income and expenditure of ‘P’ be Rs. ‘5x’ and ‘2x’, respectively And, income and expenditure of ‘Q’ be Rs. ‘5y’ and Rs. ‘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 ‘Q’ = 3 × 600 = Rs. 1,800
