2 x 2 |
5 x 2 |

Men |
Women |
|
7 |
3 |
4 u |
7 u |
3 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 = 7 u
Number of children = 4 u
Number of more men than children
= 7 u - 4 u
= 3 u
3 u = 15
1 u = 15 ÷ 3 = 5
Total number of people
= 4 u + 7 u + 3 u
= 14 u
= 14 x 5
= 70
Answer(s): 70
