17 of the people are children.
1112 of the remainder are men.
There are 18 more men than children.

Men |
Women |

11 |
1 |
2 u |
11 u |
1 u |
The number of adults is the combined repeated identity.
Make the number of adults the same by using LCM of 6 and 12.
LCM of 6 and 12 = 12
Number of men = 11 u
Number of children = 2 u
Number of more men than children
= 11 u - 2 u
= 9 u
9 u = 18
1 u = 18 ÷ 9 = 2
Total number of people
= 2 u + 11 u + 1 u
= 14 u
= 14 x 2
= 28
Answer(s): 28
