A. 5/18 B. 4/9 C. 11/18 D17/18 E.17/36
Ans: C
Explanation: Let total no. of workers be x
Number of women = x/3 and number of men = 2x/3
Women married=1/2 * x/3 = x/6
Women having children = 1/3 *x/6 =x/18
Married Men =3/4 *2x/3 = x/2
Men having Children =2/3 * x/2 = x/3
Workers with children = x/3 + x/18 = 7x/18
Hence, workers without children = x- 7x/18 = 11x/18
