Binary Question

Heres a simple bit of binary code…. translate back into english, and answer the question…

Unsurprisingly, I’m giving no hints at this stage, and I’ve removed spaces and punctuation, except the question mark.

Petals Around the Rose

Posted by Locke under Logic, Tom (26 Responds)

The name of the game is Petals Around the Rose, and that name is significant. Newcomers to the game can be told that much. They can also be told that every answer is zero or an even number. They can also be told the answer for every throw of the dice that are used in the game. And that’s all the information they get.

The person who has the dice and knows the game, rolls five dice and remarks almost instantly on the answer. For example: in Roll #1 the answer is two.

Roll #1.

4 1 6 3 6

“The answer is what?” says the new player.

“Two.”

“On that roll?”

“Yes.”

“Would it still be two if I moved the dice without turning any of them over, just rearranging the pattern?”

“I can tell you only three things: the name of the game, the fact that the answer is always even, and the answer for any particular throw. In this case the answer is two.”

“So that’s how it is. What am I supposed to do?”

“You’re supposed to tell me the answer before I tell you. I’ll give you all the time you want, but don’t tell me your theory, just the answer. If you figure it out, you don’t want to give the idea away to these other jokers around you. Make them work for the answers, too. If you get the answer right on six successive rolls, I’ll take that as prima facie evidence that you understand the game.”

“OK, roll again.”

Roll #2.

5 6 5 4 4

“I give up. What’s the answer?”

“The answer is eight.”

“Roll again.”

Roll #3.

3 5 5 5 6
The answer is fourteen.

Roll #4.

2 6 2 1 4
The answer is zero.

Roll #5.

4 3 2 1 3
The answer is four.

Roll #6.

6 5 6 2 2

What is the answer for roll #6?

Weigh an elephant

Posted by Karys under Tom (27 Responds)

There is a chinese short story telling about a minister (or whatever) who weighs the Emperor’s elephant.

How could he have done that, without having to make any giant weighing machine ?

You are not specifically asked to find the story where this came from. Here, originality and practicability are the key.

The Night After the Staff Party

Posted by Karl Sharman under Tom (10 Responds)

After one staff party, you awake to find yourself in somewhat of a quandary…

You have to break into your boss’s office. Why? After waking up with a truly nasty hangover and an even more unpleasant memory of your action at the Christmas party the night before, you realise that either you get rid of the security tapes, the photographs, and the Xerox copies of their own behind, all of which were stored in the bosses office, or you might as well clear out your desk and leave before your boss orders you to.

You easily gain access to the building and slip by the security guards and cameras without raising even the smallest hint of suspicion… until you reach your boss’s office.

There you find a note pinned to the door reading: “Attn: If you’re reading this you’re probably trying to break into my office to cover your tracks. Well, if you think I’m going to give up such juicy material without a fight, you’re wrong. If you can break past my security lock, then you deserve your stuff back. However, if you don’t, you’re fired!”

The security lock was an alphanumeric keypad with every letter of the alphabet on it and the numbers 0-9.

Below it was another note reading: “P.S. I thought I’d give you a fighting chance. The password is twelve digits long and is made up of 3 four letter long words, and here’s some more help!”

timid isle – index – true lies – timepiece – stained truth attack tom – inferior type – italian – start – main price – toil – reptilian

Unfortunately for you, your boss was a bit of a puzzle fiend….. but that wasn’t going to stop you…. Was it?

What is the code?

Letter Crunching

Posted by Karl Sharman under Tom (13 Responds)

I have a 5 letter word written in front of me. If you ask me any five letter word, I will tell you how many letters in common your word has with mine. If my word is BLACK and yours is WHITE, I will tell you 0. If my word is PLUME and yours is AMPLE I will tell you 4. Knowing that my word contains no duplicated letters, you should be able to deduce my word with only a handful of guesses or comparisons.

Then I tell you I have a list of 26 words; One for every letter of the alphabet. No duplicated letters in any words. I then take the word beginning with A and compare it to all the the other words on my list and give you the scores. I then take the word beginning with B and so on. With the exception of the X, all words are common words, so words like YURTA can be eliminated.

Your task is to find all 26 words.
