    Question

    Sneha alone can type a report in 14 days, while Reena can

    do it in 21 days. If both work together and earn Rs. 14,700 for the job, how much will Reena get?
    A Rs.5265 Correct Answer Incorrect Answer
    B Rs.5880 Correct Answer Incorrect Answer
    C Rs.6325 Correct Answer Incorrect Answer
    D Rs.5445 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the total work be 42 units (LCM of 14 and 21)

    Efficiency of Sneha = 42/14 = 3 units/day

    Efficiency of Reena = 42/21 = 2 units/day

    Total efficiency = 3 + 2 = 5 units/day

    Required amount that Reena will get = 14,700 × (2/5) = Rs. 5,880
