13 of the people are children.
57 of the remainder are women.
There are 12 more women than children.
How many people are there?
Children |
Adults |
1 x 7 |
2 x 7 |
|
Women |
Men |
|
5 x 2 |
2 x 2 |
7 u |
10 u |
4 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 = 10 u
Number of children = 7 u
Number of more women than children
= 10 u - 7 u
= 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Total number of people
= 7 u + 10 u + 4 u
= 21 u
= 21 x 4
= 84
Answer(s): 84
