13 of the people are children.
45 of the remainder are men.
There are 27 more men than children.
How many people are there?
Children |
Adults |
1 x 5 |
2 x 5 |
|
Men |
Women |
|
4 x 2 |
1 x 2 |
5 u |
8 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 5.
LCM of 2 and 5 = 10
Number of men = 8 u
Number of children = 5 u
Number of more men than children
= 8 u - 5 u
= 3 u
3 u = 27
1 u = 27 ÷ 3 = 9
Total number of people
= 5 u + 8 u + 2 u
= 15 u
= 15 x 9
= 135
Answer(s): 135
