    days and 10 days, respectively. They started working together and worked till completion of the work for which they got Rs. 14000 as wage. Find the share of ‘B’ out of total wage.

    B Rs 12000 Correct Answer Incorrect Answer
    C Rs 13000 Correct Answer Incorrect Answer
    D Rs 10000 Correct Answer Incorrect Answer

    Solution

    Let total work = 90 units {LCM of (18 and 10)} Efficiency of ‘A’ = 90/18 = 5 units/day Efficiency of ‘B’ = 90/10 = 9 units/day Wages received by ‘A’ and ‘B’ will directly proportion to their efficiency. So share of ‘B’ = 14000 × (9/14) = Rs 9000
