Women |
Men |

The number of adults is the combined repeated identity.
Make the number of adults the same by using LCM of 5 and 10.
LCM of 5 and 10 = 10
Number of women = 7 u
Number of children = 4 u
Number of more women than children
= 7 u - 4 u
= 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Total number of people
= 4 u + 7 u + 3 u
= 14 u
= 14 x 4
= 56
Answer(s): 56
