    Question

    Amit and Anaya can complete a task together in 20 days. If

    Anaya is 150% more efficient than Amit, how many days will Anaya alone take to finish the task?
    A 18 days Correct Answer Incorrect Answer
    B 15 days Correct Answer Incorrect Answer
    C 28 days Correct Answer Incorrect Answer
    D 20 days Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the efficiency of Amit alone = 4 units/day

    Then, efficiency of Anaya alone = 4 + 4 ├Ч 1.5 = 10 units/day

    So, total work = (4 + 10) ├Ч 20 = 280 units

    And so, time taken by Anaya alone to complete the work = 280 ├╖ 10 = 28 days
