Men |
Women |

13 |
1 |
4 u |
13 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 14.
LCM of 7 and 14 = 14
Number of men = 13 u
Number of children = 4 u
Number of more men than children
= 13 u - 4 u
= 9 u
9 u = 18
1 u = 18 ÷ 9 = 2
Total number of people
= 4 u + 13 u + 1 u
= 18 u
= 18 x 2
= 36
Answer(s): 36
