A student introduced me to this a few years ago. It is a challenging logic problem. I LOVE LOVE LOVE logic problems so I had a lot of fun with this. Dare I admit that it took me about 30-40 minutes to solve it?
This is a great problem to have available to throw the way of any students who finish their work early and want a little challenge (or don't want the challenge but they don't have anything else to do). You'd be surprised which students do very well with this problem - not always the "A" students!
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 keeps a
certain variety of pet. None of the owners have the same variety of pet, smoke
the same brand of cigarette or drink the same beverage.
Clues:
·
The Brit lives in the red house.
·
The Swede keeps dogs as pets.
·
The Dane drinks tea.
·
Looking from in front, 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 leftmost 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 pet fish?
