logic puzzle

3 houses require seperate gas, electric and water supplies. How are they fed without any of the supply pipes crossing??

[dundurn]

It's impossible

[chadad]

Nope, it's not impossible.
If you like I can give the solution. But it's too good a puzzle to spoil with a quick answer.
.
While you are waiting here's another one for you.
On a single sheet of paper, draw two circles, one inside the other,
The pen or pencil point must make a continuous line and not leave the paper.
Remember, just two circles one inside the other, no additional marks.

[dundurn]

If the houses are represented by points and the three supply sources are also represented by points and the plan is laid out on a single flat piece of paper, it's impossible. If you represent the houses as three squares then you can run one of the supply pipes under one of the houses. As a topological puzzle, however, that's a cheat. I seem to remember you can also do it if the puzzle is laid out on a torus - but we don't have too many building sites like that. I'm always prepared to be proved wrong but I think this one is a given.

[chadad]

You got it Dundurn, Just run one of the conduits through a house.

[chadad]

Here's another for you.
Take a forty pound bar of lead, what is the fewest pieces you would have to divide it into to weigh amounts from one to forty pounds, each in a single opperation.
EG. You cannot use a one pound weight three times to equal three pounds.
although you could add a one and a two pound weight to equal three pounds.

You've started me off now.
If S = 3 Solve the following sum.

CROSS
ROADS

1. No-one said that this is a topological puzzle, so:
Run all three supplies into the first house, take off branches to stop-****, gasmeter and fuse-box, then continue the run into the second and third houses where you do the same thing.
No crossings required anywhere.

2. The smaller circle touches the larger one. So having completed the large circle you turn the pencil inwards to draw the smaller circle, touching at that point.

3. The best I can do so far is: cut the bar into pieces weighing 1,3,9,12,15 pounds respectively.

Look at what the AB censor has done with that innocent water tap!

Can't talk about the different sexes of poultry then, pull back the spring of a gun, have a wind direction indicator, ride a certain type of horse to Banbury Cross, have a companion for the bull in an unlikely story or denote dawn by a certain type of crow.
What a narrow mind the censor has if that's the only definition he knows...

[ChuckFickens]

LOL @ chakka35

Yes that is one of the more problematic censored words on this site as it has many more innocent uses then it's single rude one.

Another problematic one is a lot of lilnks to microsoft webpages include family id in them and you can't write family id as one word, it gets censored so the links don't work!!

familyid

see

[ChuckFickens]

damm!

[chadad]

Good answer to the circle puzzle Chakka35.
But the two circles must not touch each other.
Normally two concentric rings are drawn onto a sheet of paper and you are invited to do the same without removing the pen from the paper.
( So much easier than explaining it in words )

[chadad]

Correct answer Niceboy, Congratulations.

[THECORBYLOON]

I have 1,3,5,11 and 21 for the weights.

[Panic Button]

Chakka, you may not be able to mention a male of the hen species, but you can use the anatomically correct word for a male reproductive organ - that is not censored.

[chakka35]

Yes, good answer niceboy.
Mind you, mine works as well because the original challenge did not say 'concentric'.

[north star]

1,3,9 and 27 for the weights
