    However, during the first 10 days, she did only 1/30 of the work on 30 each day. What share of the work will Ruchira have to do daily from the 11th day so that the work is completed on time?
    A 2/39 Correct Answer Incorrect Answer
    B 3/44 Correct Answer Incorrect Answer
    C 1/18 Correct Answer Incorrect Answer
    D 1/19 Correct Answer Incorrect Answer

    Solution

    According to the question The first 10 days she did only 1/30 of the work on each day   = (10 × 1/30)   =1/3  The remaining work = (1-1/3) = (3-1)/3 = 2/3 Now, Time taken to complete a task by Ruchira in 12 days = [(1/ (22-10) × 2/3] = (1/12 × 2/3)   =1/18 The required work is 18.
