    Vijay can do a piece of work in 10 days and Sanjay can

    do the same work in 15 days. If Vijay works for 4 days and got Rs. 1680, and the remaining work will completed by Sanjay, then how much rupee Sanjay earned?
    A Rs.4500 Correct Answer Incorrect Answer
    B Rs.2520 Correct Answer Incorrect Answer
    C Rs.5160 Correct Answer Incorrect Answer
    D Rs.14400 Correct Answer Incorrect Answer
    E Rs.9750 Correct Answer Incorrect Answer

    Solution

    Assume total work = LCM (10, 15) = 30 If the entire work is 30 units, Vijay can complete 3 unit per day, and Sanjay can complete 2 unit per days In 4 days, Vijay completes 12 units and got Rs.1680 i.e. Rs.140 per unit. Remaining work = (30 – 12)unit = 18 unit ∴ Sanjay earning = Rs.18 × 140 = Rs. 2520
