1 x 2 |
5 x 2 |

Women |
Men |

7 |
3 |
2 u |
7 u |
3 u |
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 = 2 u
Number of more women than children
= 7 u - 2 u
= 5 u
5 u = 30
1 u = 30 ÷ 5 = 6
Total number of people
= 2 u + 7 u + 3 u
= 12 u
= 12 x 6
= 72
Answer(s): 72
