Group C |
Group D |

1 u + 22 |
1 u |
|
| Change |
- 7 |
+ 7 |
|
| After |
1 u + 15 |
1 u + 7 |
|
Number of children that Group C had after transferring to Group D
= 1 u + 22 - 7
= 1 u + 15
Number of children that Group D had after the transfer
= 1 u + 7
Number of children in Group C more than in Group D
= 15 - 7
= 8
Answer(s): 8
