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 = 19 u
Number of children = 3 u
Number of more men than children
= 19 u - 3 u
= 16 u
16 u = 16
1 u = 16 ÷ 16 = 1
Total number of people
= 3 u + 19 u + 2 u
= 24 u
= 24 x 1
= 24
Answer(s): 24
