Women |
Men |

13 |
2 |
3 u |
13 u |
2 u |
The number of adults is the combined repeated identity.
Make the number of adults the same by using LCM of 5 and 15.
LCM of 5 and 15 = 15
Number of women = 13 u
Number of children = 3 u
Number of more women than children
= 13 u - 3 u
= 10 u
10 u = 20
1 u = 20 ÷ 10 = 2
Total number of people
= 3 u + 13 u + 2 u
= 18 u
= 18 x 2
= 36
Answer(s): 36
