    Question

    Aman can complete a task in 24 days, while Bhavna can

    finish the same task in 40 days. How long will it take for Chetan to finish the task if his efficiency is 25% more than the combined efficiency of Aman and Bhavna?
    A 22 days Correct Answer Incorrect Answer
    B 54 days Correct Answer Incorrect Answer
    C 31 days Correct Answer Incorrect Answer
    D 12 days Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let total amount of work = 120 units (LCM of 24 and 40) Work done by Aman in one day = 120 / 24 = 5 units Work done by Bhavna in one day = 120 / 40 = 3 units Combined = 5 + 3 = 8 units Chetan’s efficiency = 1.25 × 8 = 10 units/day Time taken by Chetan = 120 / 10 = 12 days
