25 of the people are children.
67 of the remainder are men.
There are 20 more men than children.
How many people are there?
Children |
Adults |
2 x 7 |
3 x 7 |
|
Men |
Women |
|
6 x 3 |
1 x 3 |
14 u |
18 u |
3 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 = 18 u
Number of children = 14 u
Number of more men than children
= 18 u - 14 u
= 4 u
4 u = 20
1 u = 20 ÷ 4 = 5
Total number of people
= 14 u + 18 u + 3 u
= 35 u
= 35 x 5
= 175
Answer(s): 175
