    B 2 days Correct Answer Incorrect Answer
    C 3 days Correct Answer Incorrect Answer
    D 4 days Correct Answer Incorrect Answer

    Solution

    (12W + 16M) × 5 = (13W + 24M) × 4 60W + 80M = 52W + 96M 8W = 16M 1W = 2M Total unit work done = (12W + 16M) × 5 = (24 + 16) × 5 = 200 units Therefore, 25 W + 50 M = 50 M + 50 M = 100 M so, Required days = 200/100 = 2 days
