Inshallaah when you have time to relax from your other 'ibada on this blessed Juma day (could be another day too) have a go at this problem. Apparantly it is produced by Albert Einstein and he claims 98% of people could not answer it. I've met two brothers (university graduates) who have managed to answer it in around an hour and one of them said it took him to the limits of uncomfortability in his problem solving skills. So now it is time to see whether your problem solving skills are as good as you think. DON'T POST THE ANSWER - you'll know you've got it right once you've met all the hints. Just post how long it took you and how easy/difficult it was. If you already know the answer then try and get it yourself. If you've already done it, then try and recall how long it took and how difficult it was.

Okay, here goes:

Facts:

1. There are 5 houses (along the street) in 5 different colors: blue, green, red, white and yellow.
2. In each house lives a person of a different nationality: Brit, Dane, German, Norwegian and Swede.
3. These 5 owners drink a certain beverage: beer, coffee, milk, tea and water; smoke a certain brand of cigar: Blue Master, Dunhill, Pall Mall, Prince and blend; and keep a certain pet: cat, bird, dog, fish and horse.
4. No owners have the same pet, smoke the same brand of cigar, or drink the same beverage.

Hints:

1. The Brit 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 (next to it).
5. The green house owner drinks coffee.
6. The person who smokes Pall Mall rears birds.
7. The owner of the yellow house smokes Dunhill.
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?

P.S. If this is unislamic please give me a heads up - I'm not that bright in terms of what's allowed and what's not.
