27 of the people are children.
910 of the remainder are men.
There are 10 more men than children.
How many people are there?
Children |
Adults |
2 x 2 |
5 x 2 |
|
Men |
Women |
|
9 |
1 |
4 u |
9 u |
1 u |
The number of adults is the combined repeated identity.
Make the number of adults the same by using LCM of 5 and 10.
LCM of 5 and 10 = 10
Number of men = 9 u
Number of children = 4 u
Number of more men than children
= 9 u - 4 u
= 5 u
5 u = 10
1 u = 10 ÷ 5 = 2
Total number of people
= 4 u + 9 u + 1 u
= 14 u
= 14 x 2
= 28
Answer(s): 28
