The number of children is the combined repeated identity.
Make the number of children the same by using LCM of 3 and 6.
LCM of 3 and 6 = 6
Number of boys = 5 u
Number of adults = 2 u
Number of more boys than adults
= 5 u - 2 u
= 3 u
3 u = 30
1 u = 30 ÷ 3 = 10
Total number of people
= 2 u + 5 u + 1 u
= 8 u
= 8 x 10
= 80
Answer(s): 80
