There were 26 more children in Group X than in Group Y. If 7 children transferred from Group X to Group Y, how many more children would be in Group X than in Group Y?
|
Group X |
Group Y |
|
Before |
1 u + 26 |
1 u |
|
Change |
- 7 |
+ 7 |
|
After |
1 u + 19 |
1 u + 7 |
|
Number of children that Group X had after transferring to Group Y
= 1 u + 26 - 7
= 1 u + 19
Number of children that Group Y had after the transfer
= 1 u + 7
Number of children in Group X more than in Group Y
= 19 - 7
= 12
Answer(s): 12
