Gilles, Robert and Michael are married to Louise, Carole and Lily. Louise’s sister is married to Michael. Gilles has never met Lily who is an only child. Who are the couples?
Answer
The couples are:
- Gilles and Louise
- Robert and Lily
- Michael and Carole
Lily is an only child, so Carole has to be Louise’s sister. This makes Carole and Micheal a couple.
Gilles has never met Lily, so this makes Gilles and Louise a couple.
The remaining couple is Robert and Lily.
