    Question

    A takes 30% longer to complete a task than B. If the

    total payment for the work is Rs. 11,500 and they complete the task together, how much should A be paid for their contribution?
    A Rs. 6,000 Correct Answer Incorrect Answer
    B Rs. 6,500 Correct Answer Incorrect Answer
    C Rs. 5,500 Correct Answer Incorrect Answer
    D Rs. 5,000 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the time taken by ‘B’ be ‘10x’ days So, time taken by ‘A’ = 10x × 1.3 = ‘13x’ days Ratio of time taken by ‘A’ and ‘B’ respectively = 13:10 So, ratio of efficiencies of ‘A’ and ‘B’ = 10:13 Therefore, share of ‘A’ = 11500 × (10/23) = Rs. 5,000 Hence, option d.
