The number of children is the combined repeated identity.
Make the number of children the same by using LCM of 7 and 14.
LCM of 7 and 14 = 14
Number of boys = 13 u
Number of adults = 2 u
Number of more boys than adults
= 13 u - 2 u
= 11 u
11 u = 22
1 u = 22 ÷ 11 = 2
Total number of people
= 2 u + 13 u + 1 u
= 16 u
= 16 x 2
= 32
Answer(s): 32
