The logic puzzle in The Philosopher's Stone book

Contents:

1 bottle moves you forwards

1 bottle moves you backwards

2 bottles have wine

3 bottles have poison

Clues:

Both bottles of wine have a bottle of poison at the left

Bottles 1 and 7 DON'T have the same content and 1 of them is the one that moves you backwards

Bottles 3 and 6 DON'T have poison

Bottles 2 and 6 have the same content

Solution:

Bottles of wine have bottles of poison at the left so bottle 1 isn't wine

Bottle 6 doesn't have poison so bottle 2 doesn't either. Wine is the only liquid besides poison that is in at least 2 bottles so bottles 2 and 6 are wine

Since bottles 2 and 6 are wine it means bottles 1 and 5 are poison

Since bottle 1 is poison it means bottle 7 is the one that moves you backwards

The potion that moves you forwards is the only available option for bottle 3 so bottle 3 is the one that moves you forwards

Poison is the only available option for bottle 4 so bottle 4 is poison
