13 |
2 |
6 u |
13 u |
2 u |
The number of adults is the combined repeated identity.
Make the number of adults the same by using LCM of 5 and 15.
LCM of 5 and 15 = 15
Number of men = 13 u
Number of children = 6 u
Number of more men than children
= 13 u - 6 u
= 7 u
7 u = 28
1 u = 28 ÷ 7 = 4
Total number of people
= 6 u + 13 u + 2 u
= 21 u
= 21 x 4
= 84
Answer(s): 84
