    Question

    Consider that 'A' and 'B' were collectively paid Rs.

    9,000 for a job. Out of this amount, 'B' received Rs. 3,000. If 'B' can finish this task solo in 48 days, determine the duration it would take for 'A' to complete the work independently.
    A 96 days Correct Answer Incorrect Answer
    B 72 days Correct Answer Incorrect Answer
    C 24 days Correct Answer Incorrect Answer
    D 20 days Correct Answer Incorrect Answer
    E 16 days Correct Answer Incorrect Answer

    Solution

    Ratio of efficiency of A:B = (9000 – 3000):3000 = 2:1 So, ratio of the time taken by ‘A’ alone to complete the work and ‘B’ alone to complete the same wor, respectively = 1:2 Therefore, time taken by ‘A’ alone to complete the work = 48/2 = 24 days
