Sally does the dusting and does not do it on Monday of Friday.
The mopping is done on Thursday.
Terry does his task, which is not vacuuming, on Wednesday.
The laundry is done on Friday and not by Uma.
Randy does his task on Monday.
Sally does dusting on
Explanation
1. Given Information (Direct Hits):
2. Analyzing Sally's Schedule:
-
We know Sally does the dusting.
-
The clues state she does not do it on Monday or Friday.
-
The available days remaining for her are Tuesday, Wednesday, and Thursday.
-
Wednesday is already taken by Terry.
-
Thursday is reserved for Mopping, but Sally's task is Dusting.
-
Therefore, the only day left for Sally is Tuesday.
3. Final Verification:
-
Since Sally is on Tuesday, and Monday (Randy), Wednesday (Terry), Thursday (Mopping), and Friday (Laundry) are accounted for, the schedule is consistent.
-
This also confirms that Vernon must be the one mopping on Thursday, as he cannot work on Tuesday.
