Solution

The correct option is A 518
The answer is option A
Let's assume the total number of workers to be x (a random multiple of 3 which easy to work with)
Number of women workers=1/3(number of workers)=x3
Number of married women=1/2(Number of Women)=x6
Number of women with children=1/3(Number of Married women)=x18
Number of women without children =Number of Married women-Number of women with children=x6x18=x9(I)

Number of men workers=2/3(number of workers)=2x3
Number of married men=3/4(Number of men)=x2
Number of men with children=2/3(Number of married men)=x3
Number of men without children =Number of Married Men-Number of Married men with children=x2x3=x6(II)

Number of people without children =(I)+(II)=x9+x6=5x18
Part of the workers without children=5x18x=518
