There were 30 more students in Group F than in Group G. If 9 students transferred from Group F to Group G, how many more students would be in Group F than in Group G?

Group F |
Group G |

| Before |
1 u + 30 |
1 u |
|
| Change |
- 9 |
+ 9 |
|
| After |
1 u + 21 |
1 u + 9 |
|
Number of students that Group F had after transferring to Group G
= 1 u + 30 - 9
= 1 u + 21
Number of students that Group G had after the transfer
= 1 u + 9
Number of students in Group F more than in Group G
= 21 - 9
= 12
Answer(s): 12
