The number of children is the combined repeated identity.
Make the number of children the same by using LCM of 3 and 7.
LCM of 3 and 7 = 21
Number of boys = 18 u
Number of adults = 7 u
Number of more boys than adults
= 18 u - 7 u
= 11 u
11 u = 22
1 u = 22 ÷ 11 = 2
Total number of people
= 7 u + 18 u + 3 u
= 28 u
= 28 x 2
= 56
Answer(s): 56
