14 of the people are children.
710 of the remainder are men.
There are 11 more men than children.
How many people are there?
Children |
Adults |
1 x 10 |
3 x 10 |
|
Men |
Women |
|
7 x 3 |
3 x 3 |
10 u |
21 u |
9 u |
The number of adults is the combined repeated identity.
Make the number of adults the same by using LCM of 3 and 10.
LCM of 3 and 10 = 30
Number of men = 21 u
Number of children = 10 u
Number of more men than children
= 21 u - 10 u
= 11 u
11 u = 11
1 u = 11 ÷ 11 = 1
Total number of people
= 10 u + 21 u + 9 u
= 40 u
= 40 x 1
= 40
Answer(s): 40
