There were 25 more pupils in Group T than in Group U. If 10 pupils transferred from Group T to Group U, how many more pupils would be in Group T than in Group U?
| |
Group T |
Group U |
|
| Before |
1 u + 25 |
1 u |
|
| Change |
- 10 |
+ 10 |
|
| After |
1 u + 15 |
1 u + 10 |
|
Number of pupils that Group T had after transferring to Group U
= 1 u + 25 - 10
= 1 u + 15
Number of pupils that Group U had after the transfer
= 1 u + 10
Number of pupils in Group T more than in Group U
= 15 - 10
= 5
