Five Sisters, Three Bedrooms
Lise, Meg, Jeanne, Ally, and Sadie are sisters. Their family has just moved into a new house. There are three bedrooms available for the five girls:

One medium-sized bedroom
One small bedroom with a bathroom
The family plans to put two girls each into the large and medium-sized rooms and one girl into the small room. Each girl makes the following demands:
-Sadie is afraid of the dark and wants to share a room.
-Lise wants a bathroom in her room.
-Meg likes the view from the medium-sized room.
-Ally wants to share a room, but not with Sadie or Meg.
-Jeanne wants her own room unless she can share with Meg.

Hint
Try making a chart.Answer
Large room: Ally and Lise.Medium-sized room: Meg and Sadie.
Small room: Jeanne.
The logic:
Sadie wants to share, so she can't be in the small room.
Lise wants a bathroom, so she can't be in the medium-sized room.
Meg has to be in the medium-sized room.
Ally wants to share, but not with Meg, so she has to be in the large room. She won't share with Sadie either, so Sadie must be with Meg in the medium-sized room.
Jeanne can't share with Meg because Sadie is sharing with Meg, so she has to have her own room.
This leaves Lise in the large room with Ally.
