    Question

    18 women can weave a carpet in 20 days. If 9 women

    started weaving the carpet and after 10 days ‘y’ more women joined them such that the remaining work got completed in 15 days, then find the value of ‘y’.
    A 5 Correct Answer Incorrect Answer
    B 7 Correct Answer Incorrect Answer
    C 9 Correct Answer Incorrect Answer
    D 11 Correct Answer Incorrect Answer

    Solution

    Total work = 18 × 20 = 360 units Work completed by 9 women in 10 days = 9 × 10 = 90 units Remaining work = 360 – 90 = 270 units Let the number of women added be ‘y’. Therefore, (9 + y) × 15 = 270 135 + 15y = 270 15y = 135 y = 9 Number of women added = 9
