Group Q |
Group R |

1 u + 26 |
1 u |
|
| Change |
- 7 |
+ 7 |
|
| After |
1 u + 19 |
1 u + 7 |
|
Number of children that Group Q had after transferring to Group R
= 1 u + 26 - 7
= 1 u + 19
Number of children that Group R had after the transfer
= 1 u + 7
Number of children in Group Q more than in Group R
= 19 - 7
= 12
Answer(s): 12
