7 x 3 |

10 u |
21 u |
9 u |
The number of children is the combined repeated identity.
Make the number of children the same by using LCM of 3 and 10.
LCM of 3 and 10 = 30
Number of boys = 21 u
Number of adults = 10 u
Number of more boys than adults
= 21 u - 10 u
= 11 u
11 u = 22
1 u = 22 ÷ 11 = 2
Total number of people
= 10 u + 21 u + 9 u
= 40 u
= 40 x 2
= 80
Answer(s): 80
