    in 27 days. If J alone takes 1.3 times the time taken by L and K working together, find the number of days J will take.

    D 19.03 days Correct Answer Incorrect Answer

    Solution

    ATQ,

    Time taken by L and K together to complete the work = (18 × 27)/ (18 + 27) = 10.8 days

    Time taken by J alone to complete the work = 1.3 × 10.8 = 14.04 days
