Sorry mate - a spooky coincidence....

I'll PM you...

New Puzzle: "As Easy As ABC"

What are the missing values A, B & C in the number grid below?



Explain your answer...

Mathematicians - Hold off posting for a while.
SquirrelDip - No programs!

[flaninacupboard]

i think A is 85, can't spot any other correlation just yet.

New Puzzle: "Clever Dead Guy"

There is a hollow stone pyramid that has a door that locks and unlocks from the inside only. There is only the one door, and that door is the only way in to or out of the pyramid. The pyramid is 50 feet high (approx. 17 metres) and has a stone base. Outside the pyramid is parked a standard white Ford Transit van.

Locals notice that the door has been locked for a few days and decide to break down the locked door to investigate. Prior to doing this, the door was the original door that came out of the "Acme Pyramid Building Kit".

Inside, a man is found hanging with his neck in a rope noose with the other end of the rope attached to the inside of the apex of the pyramid. The length of the rope and the height of the man combined leaves the man's feet about 40 feet (approx. 13 - 14 metres) clear of the ground. There is nothing else inside other than the man and the rope he's hanging from.

How'd he do it?

[flaninacupboard]

Edited so some other people can guess.

[daamon]

Yep. Heard it before?

Either way, hold off a while so others can have a crack at it...

[tgpo]

A=85
B=the value of the number under 85 -1




Edit:

B=1428? 5+12*84

[flaninacupboard]

i had heard a similar one, but after your last one immediately dismissed the stuff about pyramids and transit vans :P

[SquirrelDip]

I Just PM'd daamon what I believe to be the answer... I'll hold off and give others a try.

@daamon: Correct?

[daamon]

@ SquirrelDip - Yep, well done. For those who've guessed so far: A = 85 as proposed.

@ flaninacupboard - Cheers for the edit...

@ tgpo - Sorry, look for a different relationship...

[flaninacupboard]

thinking maybe something to do with prime numbers, 5 + next prime (7) is 12. but 85 isn't prime...

then thinking it's squares, line above would read X(1?) 2 3 so 2 squared is four. but four squared isn't 12

Is that an indirect request for some guidance...?

[flaninacupboard]

no, this will give me something to do at work tomorrow

I still have a little sketch of the power/gas problem on there, makes me look like i'm doing something technical

[daamon]

Just thinking (typing) out loud...

Yeah, I had that on my desk for a while too!!!

[4smiley20]

B=2268=84*27
C=2269

[tgpo]

A=85
B=3612
C=3613

[daamon]

@ tgpo - That's the one! Though credit has to go to SquirrelDip for getting there first.

All that remains now is for others (4smiley20, flaninacupboard) who were working on it to work out why they are the correct answers...

New Puzzle: "What's The Odd One Out"

Which of the following four is the odd one out, and why? (Guessing the correct answer is a bit lame, stating the reason as well is much more comprehensive...)

1. A sheet of clear perspex.
2. A common house brick.
3. A pane of clear glass.
4. A length of copper pipe.

Whilst there may be various "answers" that are a little abstract or simple (i.e. "the copper pipe is the only one that's a tube" kind of answers), one of the objects is the odd one out for a good reason.

@ Capmaster & SquirrelDip - D'you want the answer to the "field puzzle"?

[SquirrelDip]

I'll take a stab at it:

1. The odd one out is the brick - it's the only one that light doesn't pass through (looking through the pipe obviously).

2. The odd one out is the copper pipe - the pipe is used linearly (meters or feet) where the others would be used in an area (i.e. bricks are used to cover an area of a wall).

And yes - I'd like to hear the answer to the field puzzle.

[daamon]

SquirrelDip - I like your style... No guesses for the other 2? I will only say "Correct" when the answer has the right object and the right reason.

So, you may (but, may not) have got the right object in your 2 (!!!) guesses, but not the right reason. So - "Incorrect" to both. You cannot infer from this that these are incorrect objects, but that doesn't discount that they may be incorrect...

"The Field Puzzle" - He's a parachutist whose main and reserve have failed to deploy correctly... All the other info is just a diversion and gets people thinking in 2D and not 3D, i.e. you can approach from the air as well as along the ground...

Touche mes amis...

@daamon: I have to say I prefer the math/geometric puzzles - there generally is only one right answer (I say generally because I don't want to get into another heated ft^0.5 argument )

On these "Story" problems, as long as someone has a valid reason for making the choice they have the answer isn't necessarily incorrect - the game here is coming up with the same reason that you (or the post author) have.

3. The odd one out is the glass - it's the only one that will shatter when broken.

4. The odd one out is the Perspex - the others are generic names, Perspex is a trade name.

Field Puzzle: Not as much groaning as the 30 cent puzzle - thanks for going easy on us...

LOL - Don't resurrect that one again!

Well, I can say that in your attempts you have managed, at some stage, to guess the right object (!).

As a concession to the objectivity of this type of question, I will offer that you should (all) be looking into the properties of each object at normal everyday room temperature.

Yeah, true. But I do feel vindicated...

Answer: "What's The Odd One Out?"

SquirrelDip's comment has lead me to decide to post the answer.

The odd one out is the pane of glass. Why? Well (and this is the honest truth) glass is in fact in a fluid state with a high (and I mean high) viscosity at normal daily temperatures.

Put in plain English glass is a fluid that isn't very runny: e.g. water has a very low viscosity and is very runny, treacle is more viscous than water coz it's less runny.

If you're in any doubt, find a really old building that has the original windows (I mean, like 400+ years old) and the bottom of the windows are slightly fatter than higher up because the glass is slowly running down due to gravity over that time - that's how viscous it is!

[flaninacupboard]

damn, and i knew that as well

[daamon]

damn, and i knew that as well

Sorry... I considered SquirrelDip's comment and realised that we could be here forever trying to figure it out...

Have you figured out why A=85, B=3612 & C=3613? What the relationship is?

[tgpo]

Have you figured out why A=85, B=3612 & C=3613? What the relationship is?

So that is the Right answer?

[SquirrelDip]

@tgpo: Yes, that is the correct answer.

Another:

A man is trying to cut back his drinking and decides to begin a system. He starts his system the first day by drinking a full bottle of beer, on each day after that he cuts his consumption to half the previous day.

Even if he lives forever, how many bottles of beer will he require?

[daamon]

@ tgpo - Yes, certainly is. See here...

I know flaninacupboard was working on it, hence why I asked if he'd worked out why the answers were as you'd stated...

[flaninacupboard]

It's two.

he needs one on the first day (the full one)
another will last him forever. well, in realistic terms he'll stop when the bottle is "empty" probably after three of four days. so technically it's one bottle, and a partial bottle.

so it's either one or two, depending on your perspective

Edit:
The grid has me stumped. enlighten me!

[SquirrelDip]

@flaninacupboard: Correct:

1 + 1/2 + 1/4 + (1/2)^n ... = 2
