14 of the people are children.
57 of the remainder are men.
There are 16 more men than children.
How many people are there?
Children |
Adults |
1 x 7 |
3 x 7 |
|
Men |
Women |
|
5 x 3 |
2 x 3 |
7 u |
15 u |
6 u |
The number of adults is the combined repeated identity.
Make the number of adults the same by using LCM of 3 and 7.
LCM of 3 and 7 = 21
Number of men = 15 u
Number of children = 7 u
Number of more men than children
= 15 u - 7 u
= 8 u
8 u = 16
1 u = 16 ÷ 8 = 2
Total number of people
= 7 u + 15 u + 6 u
= 28 u
= 28 x 2
= 56
Answer(s): 56
