The number of children is the combined repeated identity.
Make the number of children the same by using LCM of 5 and 10.
LCM of 5 and 10 = 10
Number of girls = 7 u
Number of adults = 4 u
Number of more girls than adults
= 7 u - 4 u
= 3 u
3 u = 24
1 u = 24 ÷ 3 = 8
Total number of people
= 4 u + 7 u + 3 u
= 14 u
= 14 x 8
= 112
Answer(s): 112
