The Deduction

8ell, we know there are fve houses. 8e&ll assume they&re all in a row,and are numbered rom let to right. 8e know the "orwegian is in the frsthouse

House #1 #2 #3 #4 #5

Color 9 9 9 9 9

Natl "orweg 9 9 9 9

Bevg 9 9 9 9 9

Smokes 9 9 9 9 9

Pet 9 9 9 9 9

$ince the #rit lives in the red house, the "orwegian can&t. 8e also know

the "orwegian lives ne)t to the blue house, so his house isn&t blue. 8ealso know that the green house is to the let o the white house: the"orwegian can&t live in the white house since there is no house to the let,and can&t live in the green house because his only neighbor, the one tothe right, is known to live in the blue house. Thereore, the "orwegianlives in the yellow house.

8e also know the owner o the yellow house smokes %unhill, and that the"orwegian has a neighbor with a blue house ;the "orwegian only has oneneighbor, to the right.and neither are beer? and we know what house=1 smokes >and its not #lue(aster?, the only possibilities are houses =2and =5. 7eep this inormation in mind. $ince it is evident house =1cannot drink beer ;only house =2 or =5 can


4/5

$ince the %ane drinks tea, he must live in either house =2 or =5. The$wede and *erman could live in house =2, = or =5.

8e know the beer@drinker smokes #lue(aster. The only houses that coulddrink beer are =2 and =5, but since we know that =2 smokes #lends, =5must be the house which drinks beer and smokes #lue(aster, and =2 hasto be the house that drinks tea and the house o the %ane. 8e can

eliminate the possibility o the %ane&s residence being house =5.

8e know the *erman smokes 'rince. Thereore, he could not live at house=5 and thereore has to live at house =. The $wede must live at house=5: we also know house =5 raises dogs since we know the $wede raisesdogs, and that house = smokes 'rince since the *erman smokes 'rince.

The only possibility or house =!&s smokes is 'all (all: all o the others aretaken. 8e know that whoever smokes 'all (all raises birds: so house =!raises birds, and house =1 thereore has cats, since the only houses

which could have had cats were =1 and =!, and =! has been eliminated.
