13 of the people are children.
67 of the remainder are women.
There are 30 more women than children.
How many people are there?
Children |
Adults |
1 x 7 |
2 x 7 |

Women |
Men |
|
6 x 2 |
1 x 2 |
7 u |
12 u |
2 u |
The number of adults is the combined repeated identity.
Make the number of adults the same by using LCM of 2 and 7.
LCM of 2 and 7 = 14
Number of women = 12 u
Number of children = 7 u
Number of more women than children
= 12 u - 7 u
= 5 u
5 u = 30
1 u = 30 ÷ 5 = 6
Total number of people
= 7 u + 12 u + 2 u
= 21 u
= 21 x 6
= 126
Answer(s): 126
