There were 28 more children in Group A than in Group B. If 10 children transferred from Group A to Group B, how many more children would be in Group A than in Group B?
|
Group A |
Group B |
|
Before |
1 u + 28 |
1 u |
|
Change |
- 10 |
+ 10 |
|
After |
1 u + 18 |
1 u + 10 |
|
Number of children that Group A had after transferring to Group B
= 1 u + 28 - 10
= 1 u + 18
Number of children that Group B had after the transfer
= 1 u + 10
Number of children in Group A more than in Group B
= 18 - 10
= 8
Answer(s): 8
