    ‘A’ can do a piece of work in 8 days. ‘B’ can do

    40% of the same work in 16 days. If they work together for the entire time and get paid Rs.1500, then find the share of ‘A’.
    A Rs.1175 Correct Answer Incorrect Answer
    B Rs.1250 Correct Answer Incorrect Answer
    C Rs.720 Correct Answer Incorrect Answer
    D Rs.1000 Correct Answer Incorrect Answer

    Solution

    Let the total work be 16 units. (LCM of 8 and 16) Efficiency of A = 16/8 = 2 units/day Efficiency of B = (16/16) × (40/100) = 2/5 units/day Ratio of the efficiency of A : B = 2 : 2/5 = 10:2 Share of A = (10/12) × 1500 = Rs.1250
