Ratio of men to boys-----5 : 3
Ratio of women to girls----1 : 2

Since the number of girls is twice the number of boys , then we can expand the ratio women to girls to-----3 : 6

Thus, total number of units
= 5 + 3 + 3 + 6
= 17 u------510
1u------30
Diff---5-3= 2u----60

Ans: 60 more men than women
