In a certain office 1/3 of the workers are women 1/2 of the women are married and 1/3 of the married women have children if 3/4 of the men are married and 2/3 of the married men have children what part of workers are without children?

Answer»

Let the total no of workers be x 

No of women =x/3 

No of men =x-(x/3)=2x/3 

No of women having children =1/3 of 1/2 of x/3=x/18 

No of men having children=2/3 of 3/4 of 2x/3=x/3 

No of workers having children = x/8 + x/3 =7x/18 

Workers having no children=x-7x/18=11x/18=11/18 of all workers
