There were 30 more students in Group L than in Group M. If 10 students transferred from Group L to Group M, how many more students would be in Group L than in Group M?

Group L |
Group M |
|
| Before |
1 u + 30 |
1 u |
|
| Change |
- 10 |
+ 10 |
|
| After |
1 u + 20 |
1 u + 10 |
|
Number of students that Group L had after transferring to Group M
= 1 u + 30 - 10
= 1 u + 20
Number of students that Group M had after the transfer
= 1 u + 10
Number of students in Group L more than in Group M
= 20 - 10
= 10
Answer(s): 10
