Boys |
Girls |

3 u |
25 u |
2 u |
The number of children is the combined repeated identity.
Make the number of children the same by using LCM of 9 and 27.
LCM of 9 and 27 = 27
Number of boys = 25 u
Number of adults = 3 u
Number of more boys than adults
= 25 u - 3 u
= 22 u
22 u = 22
1 u = 22 ÷ 22 = 1
Total number of people
= 3 u + 25 u + 2 u
= 30 u
= 30 x 1
= 30
Answer(s): 30
