There
are five houses in a row and in five different colors.
In
each house lives a person from a different country.
Each
person drinks a certain drink, plays a certain sport, and keeps a certain pet.
No
two people drink the same drink, play the same sport, or keep the same pet.
1.
The
Brit lives in a red house
2.
The
Swede keeps dogs
3.
The
Dane drinks tea
4.
The
green house is on the left of the white house
5.
The
green house owner drinks coffee
6.
The
person who plays polo rears birds
7.
The
owner of the yellow house plays hockey
8.
The
man living in the house in the center drinks milk
9.
The
Norwegian lives in the first house
10. The man who plays baseball lives
next to the man who keeps cats
11. The man who keeps horses lives
next to the one who plays hockey
12. The man who plays billiards
drinks beer
13. The German plays soccer
14. The Norwegian lives next to the
blue house
15. The man who plays baseball has a
neighbor who drinks water.
So to
solve this on you own, don’t read further. Otherwise, follow along below.
First
draw five boxes in a row, to represent the houses.
Then put
down the basic stuff we know without other information. This includes 8, 9, and
by deduction from 9, 14.
Next
we know from 4 and 5, that the furthest right house must be the white house with
the green to its left. It can’t be shifted over any, due to the prohibition of
the middle house drinking milk.
Now
we can figure out the next two colors from 1. Since the Norwegian lives in the
first house, it can’t be red, and is yellow by default.
We
can now, knowing the yellow house, complete 7 and 11, since 11 can apply to
only one house.
This
is the tricky step. Based upon a couple of clues we need to do some guesswork.
We know the Swede can only live in one of two places, and the Dane can only
live in one of two places, based on 2, 3, and 13.
If we
consider further clues 12 and 15, then it is a pretty safe bet that the Dane
lives in the blue. You can of course reverse this, but in the next step you’ll
find logical inconsistencies. We now need to figure out which is German and
Swedish.
Like
the last step, we can make a choice. If we say the Swede is in the green house,
we run into problems in the next step with clue 12. If we assume the contrary,
we are presented with no difficulties.
We
can plug in 12, and 15 now safely.
By default,
clue 6 must be the middle house, and we can safely say from 15 that the Dane
plays baseball.
Clues
10, and for dramatic flair, 2 (which we could’ve done earlier) can now be
figured out.
Finally
we have our answer:
