    days, and 70 days respectively. A alone starts the work and work for 3 days and leaves the work, then B alone does the work for 8 days and leaves the work. If remaining work is done by C alone then for how many days has C worked?
    A 44 days Correct Answer Incorrect Answer
    B 35 days Correct Answer Incorrect Answer
    C 16.5 days Correct Answer Incorrect Answer
    D 45 days Correct Answer Incorrect Answer
    E 56 days Correct Answer Incorrect Answer

    Solution

    Total work = LCM of 15, 45 and 90 = 90 units Unit per day of A = 90/15 = 6 Unit per day of B = 90/45 = 2 Unit per day of C = 90/90 = 1 Units of work done by A in 3 days = 6 ├Ч 3 = 18 units Units of work done by B in 8 days = 8 ├Ч 2 = 16 units Remaining work = 90 тАУ (18 + 16) = 56 units So, C has worked for 56/1 = 56 days
