    ‘A’ can do a piece of work in 15 days. ‘B’ can

    do 60% of the same work in 20 days. If they work together for the entire time and get paid Rs.1450, then find the share of ‘A’.

    C Rs.720 Correct Answer Incorrect Answer
    D Rs.1000 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the total work be 60 units. (LCM of 15 and 20) Efficiency of A = 60/15 = 4 units/day Efficiency of B = (60/20) × (60/100) = 9/5 units/day Ratio of the efficiency of A : B = 4 : 9/5 = 20:9 Share of A = (20/29) × 1450 = Rs.1000
