Einstein wrote this test and said that 98% of the people can't solve it... Let's hope you are one of the remaining 2%. There's only one solution for this problem. There are 5 houses of 5 different colours. In each house lives a person of a different nationality. Those 5 people drink different drinks, smoke cigarettes of a different brand and have a different pet. None of them has the same pet, smokes the same cigarette or drinks the same drink. Question: Who has the fish? Tips: The englishman lives in the red house. The swedish has a dog as a pet. The Dane drinks tea. The green house is at the left side of the white one. The person who lives at the green house drinks coffee. The person who smokes Pall Mall raises birds. The owner of the yellow house smokes Dunhill. The man that lives in the house that is in the middle drinks milk. The norwegian lives in the first house. The man that smokes Blends lives next to the one that has cats. The man that raises horses lives next to the one that smokes Dunhill. The man that smokes Bluemaster drinks beer. The german smokes Prince. The norwegian lives next to the blue house. The man that smokes Blends is neighbour of the one that drinks water. ........................................... This puzzle is brilliant, imo. Took me about 20 minutes to solve. I'll post the answer later if need be.
