Einstein's Logic Puzzle That 98% of the World Population Can't Solve. Answered

There are 5 houses each with a different color. Their owners, each with a unique heritage, drinks a certain type of beverage, smokes a certain brand of cigarette, and keep acertain variety of pet. None of the owners have the same pet, smoke the same brand of cigarette or drink the same beverage.

  • The Brit lives in the red house.
  • The Swede keeps dogs as pets.
  • The Dane drinks tea.
  • The green house is just to the left of the white house.
  • The green house's owner drinks coffee.
  • The person who smokes Pall Malls raises birds.
  • The owner of the yellow house smokes Dunhill.
  • The man living in the center house drinks milk.
  • The Norwegian lives in the first house.
  • The man who smokes Blends lives next to the one who keeps cats.
  • The man who keeps a horse lives next to the man who smokes Dunhill.
  • The owner who smokes Bluemasters also drinks beer.
  • The German smokes Prince.
  • The Norwegian lives next to the blue house.
  • The man who smokes Blends has a neighbor who drinks water.
Who owns the fish?

You may now thank me for ruining your holiday.

Here's what I have:
Yellow-norwigian-Dunhill
Blue-horse-water-German?-Prince?
Red-Brit-milk-Blends
Green-Coffee-cats-German?-Prince?
White-swede-Bluemasters-beer.

I got the colors, and maybe a few other things, but it gets mucky after that.

I think it is the Brit, but my friend says it's the German.

I like these sorts of things, a little bit of time and little knowledge of anything in particular make me feel nice and smug for a short while. My process also says it is the German who keeps fish. Once I figured out the Norwegian drank water, it all fell together. It was like a Sudoku without numbers.

Come to think of it, now I think it's the Frenchman who keeps the fish.. =)

I think it should read:
Einstein's Logic Puzzle That 80% of Instructablers will be able to solve.
That 98% might holds true if it was posted in someplace like Myspace though.

There're just a lot of nerds here =P

It is simply an IQ test, administered by a professional test taker. Whether they give it, or a psychologist that they approve makes little difference. :-) One of their tests has an ambiguous question in it, find that one and point it out and you freak out the test taker (if they recognize what you are trying to explain to them LOL).

Einstein suggested that it could only be figured out by 2% of the population

that really only means that only 2 % know how to figure out this kind of puzzle, since it is the same method used on the simpler ones *sigh*

maybe because it is late at night, but I am confused :-)

These puzzles are fairly straightforward, solved in exactly the same way for each one.

These puzzles, if a simple chart is made of the characters, the objects, and the conditions. Then, program like, you run the list until all facts have been gleaned from the puzzle. In this case, it is a little more tedious than normal...time consuming...

yeah its the German, my 9th grade math teacher did the same thing. Also i heard somewhere that it is more than 2% now, probably because of population increase or everyone could just be getting smarter (is smarter even a word?)
