Einstein's Intelligence Quiz: Answer

Einstein wrote this quiz last century. He said that 98% of the people in the world cannot solve the quiz.

• There are 5 houses in 5 different colors
• In each house lives a person with a different nationality
• These 5 owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet
• No owners have the same pet, smoke the same brand of cigar or drink the same drink.

The question is: Who owns the fish?

The answer: The German is the only one without a pet, therefore he must be the one who owns the fish.
If you got it right you are one of the 2% who can. Congratulations.

I solved it in around 20 minutes, although I didn't time it officially.
