    17/36

    Incorrect Answer

    4/9

    Incorrect Answer

    5/18

    Incorrect Answer

    11/18

    Correct Answer
    Explanation:
    Let, total number of workers be N .
    Then number of women = N/3
    Number of men = 2N/3
    Number of women having children = 1/3 of 1/2 of N/3 = N/18
    Number of men having children = 2/3 of 3/4 of 2N/3 = N/3
    Number of workers having children = N/18 + N/3 = 7N/18
    Number of workers having no children = N - 7N/18 = 11N/18
    =11/18 of all workers
