110 of the people are children.
1718 of the remainder are women.
There are 15 more women than children.
How many people are there?

Adults |
1 x 2 |
9 x 2 |
|
Women |
Men |
|
17 |
1 |
2 u |
17 u |
1 u |
The number of adults is the combined repeated identity.
Make the number of adults the same by using LCM of 9 and 18.
LCM of 9 and 18 = 18
Number of women = 17 u
Number of children = 2 u
Number of more women than children
= 17 u - 2 u
= 15 u
15 u = 15
1 u = 15 ÷ 15 = 1
Total number of people
= 2 u + 17 u + 1 u
= 20 u
= 20 x 1
= 20
Answer(s): 20
