Einstein's puzzle

Ik heb er even over gedaan, maar ik heb het raadsel opgelost!
Men zegt dat het raadsel door Einstein als klein jongetje is bedacht, maar volgens Wikipedia kan dat niet omdat Pall Mall sigaretten toen nog niet bestonden.
Een andere claim: 98% van de mensen die het raadsel onder ogen krijgen, kan het niet oplossen. Lijkt me ook onzin, want met genoeg redeneren en pen en papier (!!!) kom je er echt wel!
Veel succes!

There are exactly 5 houses on the street, in a line running from left to right. Each house is a different colour, and each has exactly one owner.

The 5 owners each drink a certain drink, each smoke a certain brand of cigarette, and each have a certain pet.

• No owner drinks the same drink as any other.
• No owner smokes the same brand of cigarettes as any other.
• No owner has the same pet as any other.

The following statements are true:

1. The British man lives in the red house.
2. The Swedish man has a dog for a pet.
3. The Danish man drinks tea.
4. The green house is just to the left of the white house.
