Seven different events- Craft, Dancing, Drawing, Football, Hockey, Singing and Swimming are scheduled in a week from Monday to Sunday, but not necessarily in the same order.
Only one event is scheduled for a day.
Only Football is scheduled before Singing. Either three or four events are scheduled between Hockey and Singing.
| | Case 1 | Case 2 |
| Days | Events | Events |
| Monday | Football | Football |
| Tuesday | Singing | Singing |
| Wednesday | | |
| Thursday | | |
| Friday | | |
| Saturday | Hockey | |
| Sunday | | Hockey |
Less than four but more than one event is scheduled between Craft and Drawing.
Craft and Drawing are not scheduled on Thursday.
| | Case 1 | Case 1a | Case 2 | Case 2a |
| Days | Events | Events | Events | Events |
| Monday | Football | Football | Football | Football |
| Tuesday | Singing | Singing | Singing | Singing |
| Wednesday | Craft | Drawing | Craft | Drawing |
| Thursday | | | | |
| Friday | | | | |
| Saturday | Hockey | Hockey | Drawing | Craft |
| Sunday | Drawing | Craft | Hockey | Hockey |
Dancing is scheduled immediately before Craft. Thus, case 1, case 1a and case 2 are invalid. Therefore, the final arrangement is:
| Days | Events |
| Monday | Football |
| Tuesday | Singing |
| Wednesday | Drawing |
| Thursday | Swimming |
| Friday | Dancing |
| Saturday | Craft |
| Sunday | Hockey |
Swimming is scheduled immediately before Dancing.
