This quiz is supposed to have been written by Einstein. He said that 98% of the people in the world cannot solve the quiz. Could you be among the other 2%?

• There are 5 houses, each is a different colour
• In each house lives a person of a different nationality.
• These 5 owners all drink a certain beverage, smoke a certain brand of cigar and keep a certain pet.

1: The Briton lives in a red house.
2: The Swede keeps dogs as pets
3: The Dane drinks tea
4: The green house is on the left of the white house (they are also next door to each other)

8: The man living in the house right in the center drinks milk
9: The Norwegian lives in the first house
10: The man who smokes Blend lives next to the one who keeps cats
11: The man who keeps horses lives next to the man who smokes Dunhill
12: The owner who smokes Blue Master drinks beer
13: The German smokes Prince
14: The Norwegian lives next to the blue house
15: The man who smokes Blend has a neighbor who drinks water.

The question is: WHO KEEPS FISH?

The answer:

9: The Norwegian lives in the first house

	1	2	3	4	5

Man	Norwegian
Pet
Smoke
Drink

14: The Norwegian lives next to the blue house

	1	2	3	4	5

Man	Norwegian

8: The man living in the house right in the centre drinks milk

	1	2	3	4	5
Colour		Blue
Man	Norwegian

Smoke
Drink			Milk

4: The green house is on the left of the white house (they are also next door to each other)
5: The green house owner drinks coffee

	1	2	3	4	5
Colour		Blue		Green	White
Man	Norwegian
Pet
Smoke
Drink			Milk	Coffee

(Note – Since House 2 we already know is blue, and the green and white house are next to each other, they must be 3 and 4 OR 4 and 5. However the owner of House 3 drinks milk. So 4 must be the Green House and 5 must be the White House)

1: The Briton lives in a red house.

	1	2	3	4	5
Colour		Blue	Red	Green	White
Man	Norwegian		Briton
Pet
Smoke
Drink			Milk	Coffee

7: The owner of the yellow house smokes Dunhill

	1	2	3	4	5

11: The man who keeps horses lives next to the man who smokes Dunhill

	1	2	3	4	5
Colour	Yellow	Blue	Red	Green	White
Man	Norwegian		Briton
Pet		Horses
Smoke	Dunhill

3: The Dane drinks tea
12: The owner who smokes Blue Master drinks beer
15: The man who smokes Blend has a neighbor who drinks water

	1	2	3	4	5
Colour	Yellow	Blue	Red	Green	White
Man	Norwegian	Dane	Briton
Pet		Horses
Smoke	Dunhill	Blend			Blue Master
Drink	Water	Tea	Milk	Coffee	Beer

(OK – here is where we get all the drinks sorted out. The Dane could be 2 or 5. The person who smokes Blue Master could also be 2 or 5. However the Dane can’t be 5, otherwise House 2 would be the Blue Master smoker and beer drinker, which would only leave House 1 for the water drinking neighbour; this doesn’t work, since this would now make House 2 the Blend smoker. So the Dane is in House 2, etc)

13: The German smokes Prince

	1	2	3	4	5
Colour	Yellow	Blue	Red	Green	White
Man	Norwegian	Dane	Briton	German
Pet		Horses

	1	2	3	4	5

Man	Norwegian	Dane	Briton	German	Swede
Pet		Horses			Dogs
Smoke	Dunhill	Blend		Prince	Blue Master
Drink	Water	Tea	Milk	Coffee	Beer

6: The person who smokes Pall Mall rears birds

	1	2	3	4	5
Colour	Yellow	Blue	Red	Green	White
Man	Norwegian	Dane	Briton	German	Swede
Pet		Horses	Birds		Dogs
Smoke	Dunhill	Blend	Pall Mall	Prince	Blue Master

10: The man who smokes Blend lives next to the one who keeps cats

	1	2	3	4	5

Man	Norwegian	Dane	Briton	German	Swede
Pet	Cats	Horses	Birds		Dogs
Smoke	Dunhill	Blend	Pall Mall	Prince	Blue Master

Which only leaves one gap.

Who keeps Fish? The German.
