Men |
Women |

20 |
1 |
6 u |
20 u |
1 u |
The number of adults is the combined repeated identity.
Make the number of adults the same by using LCM of 7 and 21.
LCM of 7 and 21 = 21
Number of men = 20 u
Number of children = 6 u
Number of more men than children
= 20 u - 6 u
= 14 u
14 u = 28
1 u = 28 ÷ 14 = 2
Total number of people
= 6 u + 20 u + 1 u
= 27 u
= 27 x 2
= 54
Answer(s): 54
