    for Rs. 6600. P can finish the work alone in 12 days, and Q can complete it alone in 10 days. If they work together, what will be the difference in the amounts they receive for the work?

    B Rs. 600 Correct Answer Incorrect Answer
    C Rs. 350 Correct Answer Incorrect Answer
    D Rs. 420 Correct Answer Incorrect Answer

    Solution

    ATQ, Let the total work be '60x' units. Efficiency of P = 60x ÷ 12 = 5x units/day Efficiency of Q = 60x ÷ 10 = 6x units/day Required difference = 6600 × {(6x - 5x) ÷ 11x} = 6600 × (1/11) = Rs. 600
