Answer : 3. "11/18"
Explanation :
Answer: C) 11/18 Explanation: Let the total number of workers be x. Then, Number of women = x/3 and number of men = x - x/3 = 2x/3 Number of women having children = x/18 Number of men having children = x/3 Number of workers having children = (x/18) + (x/3) = 7x/18 Therefore, workers having no children = x - 7x/18 = 11/18 of all workers.
