Aus dem Haeuschen (Posted on 2008-03-05) Difficulty: 3 of 5

Persons 1-5 occupy houses (in that order) on a ring road. The houses are painted amber, blue, chartreuse, denim and ecru (not necessarily in that order).

Fact 1. Person #1 presently lives in a house that is neither ecru nor denim.

Fact 2. One and only one of Person #1 and Person #3 presently live next to the blue house.

Fact 3. Some time ago, two people switched houses. As a result of the switch, one and only one of Person #2 and Person #4 got a new neighbour.

Fact 4. Either both of amberís neighbours were changed in the switch, or else both of amber's neighbours remained unchanged.

Who lives in the chartreuse house?

Note: Aus dem Haeuschen is German slang. Haeuschen, (cottage) is used as a metaphor for for "brain". Thus, Aus dem Haeuschen means, more or less, out of one's mind, in the sense of being enthusiastic about something.

Clarification: Each person (and each house) has two neighbours, namely the person living to the left and the right. If the left neighbour and the right neighbour change houses, the occupant in the middle does not get any new neighbours.

I just started to try a random possibility of distribution of the people and the houses. Either it was a long shot or I just did something wrong, but it seems to comply with the facts stated. In the proposed scenario one can infer that it is possible for # 1 to be the owner of the Chartreuse (what the hell is chartreuse?).<o:p></o:p>

Since I'm not a native english speaker, I might have misunderstood the problem. If it's the case I apologize in advance.<o:p></o:p>


                                   4 - Ecru<o:p></o:p>

            2 - Amber                         1 - Chartreuse    <o:p></o:p>

                     5 - Denim           3 - Blue<o:p></o:p>


1- # 1 is not in Ecru or Denim<o:p></o:p>

2 - Only #1 lives next to Blue<o:p></o:p>

<st1:Street w:st="on"><st1:address w:st="on">3 - #4</st1:address></st1:Street> and #5 switched places. # 4 got a new neighbor<o:p></o:p>

4 - 2# is amber and both neighbors remained unchanged after the switch.<o:p></o:p>
