  • Options
  • A. 5/11
  • B. 4/9
  • C. 11/18
  • D. 17/36

  • Correct Answer
  • 11/18 

    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
