Self-Referential Aptitude Test

phrontister · 2009-07-26 21:31:27

Here's a great logic puzzle that I found on the internet...where it's widely discussed. It took me some time to work out what on earth the author was driving at - and considerably longer to solve it.

This photo may help to throw some light on the concept of self-referentialism:-

I remember that! I did it eventually, but it took me quite a while.
There's something special about the answer though, so I can still remember it easily.

Here's an online version if anyone's interested.

Hi phrontister!

It was a really Terrific Teaser!!

I solved it Last Night before going to

Here's the Outline of my Approach...

I'm submitting the solution in Parts because somehow i feel the necessity for the Solution Images to be together with the Explanations. Moreover, its too lengthy for me to type in just one go... I'll take a few hour's break!!!!!

The Questionnaire should look like this after completing Part1...

Hi ZHero,

You're definitely not the only person to have tried this puzzle and lost sleep because of it!! I lost plenty!

Glad you thought it was a good teaser too!

But...have you actually solved each question, or just those you've ticked on the questionaire? You're supposed to solve the lot, and only then will you be able to make sense of what mathsyperson wrote...that "there's something special about the answer".

I hope you didn't think that the aim was just to solve the last question, with questions 1 to 19 being there only to help you solve Q20!

I agree.. This world is full of all sorts and no wonder you may one day find your own reflection!!

It was a Feel of Content/Satisfaction afterwards!

A little patient there my friend! I'm (slowly) posting the step by step approach!

I've perhaps got what mathsy meant there! It's really special
I'll come to that....

Hi phrontister!

Now you can perform a

of the above method and let me know of any flaws that may exist... There are only 20 Steps

Anyways... It was a really nice puzzle and now I'm gonna start with the other one's!

phrontister · 2010-05-18 22:55:10

Hi ZHero!

All correct and

!

I'll dig up my solving notes because I'd like to see how our approaches compare; and I'll get back to you, but that might take a little while.

Glad you liked it...and thanks for posting your comments and strategy!

ZHero · 2010-05-19 01:25:06

I can wait till then (just don't forget ok)

And i'd like to know what's special bout the answer according to you and mathsyperson??
Might be that I couldn't discover it....

Hi ZHero,

'k.

And i'd like to know what's special bout the answer according to you and mathsyperson??

I shouldn't have drawn your attention to it...it's rather lewd. Sorry.

ZHero · 2010-05-20 20:19:44

I won't coerce you but lemme guess... has it got something to do with anagrams?
I found a lewd one with the answers
