Group K |
Group L |

1 u + 27 |
1 u |
|
| Change |
- 7 |
+ 7 |
|
| After |
1 u + 20 |
1 u + 7 |
|
Number of children that Group K had after transferring to Group L
= 1 u + 27 - 7
= 1 u + 20
Number of children that Group L had after the transfer
= 1 u + 7
Number of children in Group K more than in Group L
= 20 - 7
= 13
Answer(s): 13
