13 of the people are children.
67 of the remainder are men.
There are 10 more men than children.
How many people are there?
Children |
Adults |
1 x 7 |
2 x 7 |
|
Men |
Women |
|
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 men = 12 u
Number of children = 7 u
Number of more men than children
= 12 u - 7 u
= 5 u
5 u = 10
1 u = 10 ÷ 5 = 2
Total number of people
= 7 u + 12 u + 2 u
= 21 u
= 21 x 2
= 42
Answer(s): 42
