The number of children is the combined repeated identity.
Make the number of children the same by using LCM of 2 and 6.
LCM of 2 and 6 = 6
Number of girls = 5 u
Number of adults = 3 u
Number of more girls than adults
= 5 u - 3 u
= 2 u
2 u = 24
1 u = 24 ÷ 2 = 12
Total number of people
= 3 u + 5 u + 1 u
= 9 u
= 9 x 12
= 108
Answer(s): 108
