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 boys = 7 u
Number of adults = 2 u
Number of more boys than adults
= 7 u - 2 u
= 5 u
5 u = 25
1 u = 25 ÷ 5 = 5
Total number of people
= 2 u + 7 u + 3 u
= 12 u
= 12 x 5
= 60
Answer(s): 60
