    B Rs.500 Correct Answer Incorrect Answer
    C Rs.350 Correct Answer Incorrect Answer

    Solution

    ATQ;
    Let monthly income of ‘Pawan’, ‘Qureshi’ and ‘Ram’ be Rs. ‘4x’, Rs. ‘7x’ and Rs. 5x, respectively.
    ATQ;
    ‘4x’ = 2800
    Or, x = 700
    So, monthly income of ‘Ram’ = ‘5x = 5 × 700 = Rs. 3,500
    Let monthly expenditures of ‘Pawan’, ‘Qureshi’ and ‘Ram’ be Rs. ‘5y’, Rs. ‘4y’ and Rs. ‘8y’, respectively.
    Monthly savings of ‘Pawan’ = Rs. 800
    ATQ,
    (2800 – 5y) = 800
    Or, 5y = 2000
    So, y = 400
    So, monthly expenditure of ‘Ram’ = 8y = 4 × 400 = Rs. 3,200
    Therefore, monthly saving of ‘Ram’ = (3500 – 3200) = Rs. 300
