Solution
The correct option is C1118 Let the total number of workers be x. Then, Number of women = x3 and number of men = (x−x3) = 2x3 Number of women having children = 13of12ofx3=x18. Number of men having children = 23of34of2x3=x3. Number of workers having children = (x18+x3)=7x18. Therefore, workers having no children = (x−7x18)=11x18=1118 of all workers. Hence, option (C) is the correct answer.
