    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Initial amount with 'X' = 5600 × (4/20) = Rs. 1120

    Initial amount with 'Z' = 5600 × (3/20) = Rs. 840

    Initial amount with 'W' = 5600 × (7/20) = Rs. 1960

    Amount given by 'Y' to 'Z' = {(1120 + 1960) ÷ 2} × 0.60 = 1540 × 0.60 = Rs. 924

    Final amount with 'Z' = 840 + 924 = Rs. 1764

    Therefore, required average = (1120 + 1764) ÷ 2 = Rs. 1442
