    Anurag can finish a task in 60 days, while Bhuvan can

    complete the same task in 80 days. Anurag begins working alone, and after 39 days, Bhuvan joins him. How many more days will Anurag and Bhuvan take together to complete the remaining work?
    A 20 days Correct Answer Incorrect Answer
    B 15 days Correct Answer Incorrect Answer
    C 12 days Correct Answer Incorrect Answer
    D 14 days Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ;
    Let the total amount of the work = 240 units (LCM of 60 and 80)
    AnuragтАЩs efficiency = 240/60 = 4 units per day
    BhuvanтАЩs efficiency = 240/80 = 3 units per day
    Amount of the work done by A in 39 days = 39 ├Ч 4 = 156 units
    Remaining amount of the work = 240 тАУ 156 = 84 units
    Remaining amount of the work done by Anurag and Bhuvan together = 84/7 = 12 days
