an officemate sent me this riddle..
Einstein wrote this riddle this century. He said 98%
of the world could not solve it.

2. The five owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet.

| house 1 | house 2 | house 3 | house 4 | house 5 |
| -------- | ------- | ------- | ------- | ------- |
| british | british | british | british | british |
| swede | swede | swede | swede | swede |

nakakatamad na ilagay lahat..
next thing to do.. well you have to use the select-and-terminate method. when one is selected, terminate the others that have the same option. hmmm use the easiest hints 1st by the way.
ex.
i. The Norwegian lives in the first house.
since the norwegian is in the 1st house, obviously he is not in the 2nd 3rd 4th nor 5th. so norwegian shall be terminated from the list in house 2, 3, 4, and 5.
next hint:
n. The Norwegian lives next to the blue house.
so the next house is blue!
*duh* and then remove from the option of colors the blue from house 1,3,4, and 5
looking for other hints:
h. The man living in the center house drinks milk.
so this time you have something for your beverage, milk in the middle so remove it from house 1,2,4 and 5.
im gonna have a hard time explaining this....
*shrugsgoing back to the 1st hint "The Brit lives in the red house". still useless? just remember these points for that riddle.
1. if the house is blue then he's no brit.
2. if the house is red then brit is in.
3. if the house isnt red then brit is not in.
4. if the brit doesnt live in that house then the house aint red.
then move to the next hint and so on..
here's how i did the process.
h. The man living in the center house drinks milk. -- note: milk
i. The Norwegian lives in the first house. -- as described
n. The Norwegian lives next to the blue house. --
c. The Dane drinks tea. - remove tea from the drink list of house 1 & 3
a. The Brit lives in the red house - assume that the red house is house 5. then match if theres a conflict.
d. The green house is on the left of the white house. - then we can put the house locations at this moment.
e. The green house's owner drinks coffee. -
then u find green house owner drinks coffee. if green house is left of white. putting up the pattern like
3-green 4-white 5-red
it is noted that middle house drinks milk. so that cant be green if green house owner drinks coffee isnt it? so we find this answer.
3-red 4-green 5-white 2-blue (and of course remaining 1 is then set to yellow)
3-brit 4- 5- 2- (1 is norwegian as previously given)
g. The owner of the yellow house smokes Dunhill. - there it goes. house 1
l. The owner who smokes Bluemasters drinks beer. - remove bluemasters from house 1,3&4. makes house 1 a water drinker
m. The German smokes Prince. - remove prince from house 3
b. The Swede keeps dogs as pets. - remove dog from house 1 and 3
j. The man who smokes Blends lives next to the one who keeps cats. - remove cats option from house 4&5
k. The man who keeps the horse lives next to the man who smokes Dunhill. - ok pet of house 2 is a horse. this also concludes that house 2 cannot be swede
o. The man who smokes Blends has a neighbor who drinks water. - house 2 again. :D
f. The person who smokes Pall Mall rears birds. - remove the possibility that norwegian has a pet bird
l. The owner who smokes Bluemasters drinks beer. - remove beer from house 2 who actually smokes blends. whats left is that he drinks tea. then leaves house 5 as the beer drinker. who, as a result the bluemaster smoker. and of course crossing out the other options that were already selected. house 3 owner leads to be the pall mall smoker, and house 4 owner as the prince smoker.
m. The German smokes Prince. - house 4 then is german. house 2 then is left with the Dane option. and that makes house 5 as the swede.
b. The Swede keeps dogs as pets. - there goes our answer
f. The person who smokes Pall Mall rears birds. - its the brit! its the brit!!
j. The man who smokes Blends lives next to the one who keeps cats. - its actually obvious already that the german was left with only fish as an option so that makes the norwegian as the cat owner. and our riddle is already solved.
