That thought had crossed my mind. Ten furlongs per fortnight (less than 2 millimeters per second) is very slow for a tortoise. That's even slow for a snail.

On the other hand, the riddle does put us in a peculiar universe where tortoises have extramarital affairs and quaff bottles of champagne. It's hard for me to imagine how slow a speed, or the cause of the slowness, would constitute out-of-the-ordinary in such a universe. :smile:
The point, as with most word problems, is to cut to the quick of the narrative and determine what's being asked. Here the problem is simply to figure out if "10 furlongs per fortnight" is fast or slow for a tortoise. The particular reasons offered that the tortoise might be going faster or slower than he otherwise would are merely entertaining and decorative mud intended to slow you down in penetrating to the core problem.

I think I might have it, maybe. If so, this is my guess: 312211

The rule for generating the next number is to describe the number of consecutive digits in the present number (starting the most significant digits) and state those digits. Remove all punctuation and non-number words. Start with '1'.

1
So the next number is the numerical version of the statement,
One '1' ==> 11
The next number is the numerical version of the statement,
Two '1's == > 21
The next number is the numerical version of the statement,
One '2' and one '1' ==> 1211
The next number is,
One '1', one '2', and two '1's ==> 111221

Which brings us to the answer,
Three '1's, two '2's, and one 1 ==> 312211

Correct! And I thought that would stump some people :[

It almost did! :smile: I started out ...
... assuming the numbers were in ternary (base 3), converted them to decimal, then got a whole lot of nowhere. The sentence translation thing was mostly stumbling luck right before I was about to give up. :redface:

Good job getting the right answer! I also started following the base 3 red herring, then just gave up.

I went to a certain FF Restaurant last night and when I was given my order number I noticed it was 411. I thought, "That's an odd number!," and decided to see if it was prime. It turns out to be the product of 3*137.

And that's the 411 on 411.

211,311,811,911 are prime, but
111,411,511,611,711,1011 are composite. 711 is the odd man out, having three factors. All the others have two.

These are interesting:

111 = 3*37
411 = 3*137
711 = 3*237 (but unlike the others, 237 is not prime.)
1011=3*337, etc.


None of the '11' composites thus far have 11 as a factor. The first composite '11' number to have 11 as a factor is: 1111. What is the last? Is there some number ending in 11 having 11 as a factor larger than which there can be no others with those features? If not, then we have the theorem: There is an infinite number of numbers ending in 11 having 11 as a factor. When you finish this sentence you have 30 seconds to prove the theorem.

Q.E.D. But I was just about sure someone would prove it by proving it for all numbers: The number of numbers, n, ending in n, having n as a factor, is infinite.
(Not sure I phrased that right.)

The way you generate one is pick any number and precede it by itself or a multiple of itself (works for single digits, any number of digits). Since an infinite number of multiples of any number is possible, there will be an infinite number of numbers that fit the criteria (ending in n and having n as a factor).

I would guess that the Princess is not stationery, therefore she may choose which of the suitors to approach.

See if you can get what's going on before the end of the video:

I thought it was a flat piece of paper with perspective drawings, but I was wrong.

I don't have an answer to all of them. I got 9 of them:

1, 2, 6, 7, 8, 9, 11, 12, 14

If you guess those you win (because I only have an answer to those).

(Number 4 is puzzling me, looks like some sort of series or sequence)

So, 3 is:
Signs
4 is:
Mean Girls
5 is:
Sum of All Fears
I think 13 is:
XXX (w/ Vin Deisel)
15 should be:
Speed
16 is:
127 Hours

I don't know what 10 is...I have an idea, but it doesn't seem even close

Awesome! It was supposed to be the other ones, but since you got those even better. To think number 4 was "mean".

Number 10 sounds like Iron Man, but I see no man anywhere. So nope.

Number 2 is
The Matrix

Number 6 is
Snakes on a Plane

Number 8 is
Alpha and Omega

Number 9 is
The Exorcist

Number 12 is
Vertical Limit

Number 14 is
E

So that still leaves
1, 7, 10, 11 and 13.

[Edit:
Number 1 might be
Sin City
but I'm not 100% on that.]

Number 14 is almost correct. What is behind the "e" number?
Yup, number one is correct! As well as the others.

I got number 10: 1970's war film.

I think that leaves 7 and 11 left.

Nope, the others are right, but these ones are different. Think about programming and the internet.

I really don't think its social network on account of the one man out of the network on the other hand http://en.wikipedia.org/wiki/Outlier and http://www.imdb.com/title/tt2703688/ seem to fit better.
I haven't seen it, but it doesn't ring any possibility in my opinion (maybe because I haven't seen it). I think it's the one you think it's not.

Nope, in programming that block of text has a name. :biggrin:

number 7 - looper?
 
  • #953
No, but you are so close. The movie title contains the word Loop in it. Hint: It's so easy. The movie is British, is not American. It is a parody of Anglo-American politics. The girl there is asking: "Where am I?"

Yes! :-p

I will expect a witty rebuttal to that.

But you must be a non veg

Well the next one then, you've been given a barrel of beer and I've removed some quantity from it (Hic!).
You are to determine whether the quantity removed was more than half, half or less than it...without using any instruments whatsoever except your 'selves'. Be advised that you are not to drink it, or dunk your hand, legs, head or anything else in it. After solving the puzzle you may drink this hypothetical beer up or dump it on my head. (preferably the later)
Good Luck!
And no googling ZBS (or anyone else)...
Use those (P)Fing brains of yours.

Okay, here's one that I came up with years ago. It may not be my best, but here it is anyway. 'Haven't seen a riddle in awhile, so here it goes.
------------------------------
Riddle:

Reclusive, young Wendy Wolf, new to her neighborhood of Worland, Wyoming, recently moved into her new worldly apartment. Wendy was wanton to get by independently within the world. It was her first time living within the city and away from the wilderness. Wendy woefully kept to herself, but wished for company.

Weary of wallowing in solitude, Wendy invited all her new neighbors over for a rewarding dinner party.

Many guests arrived and the evening started wonderfully. With wild music and whimsical dancing, the evening went on well.

While Wendy was away preparing the walnuts, wine and wishbone dinner, the Sun sank away and the Moon arose, and her guests began to wander. When the time came for dinner, Wendy was alone. Wendy wondered why have all her guests went away? Wendy stood wanting for answers. "What has went awry?"

Question: What did Wendy neglect regarding the dinner party in her new home? And why?

-----------------------
Hints:
  • The town of Worland, Wyoming, in particular, has nothing to do with the answer. (I picked that town at random.)
  • I'm supposing a person in Wendy's situation would probably not have made the same oversight. And typical guests may not have behaved the same way either. But such oversights and actions are within the realm of possibilities. So there's that.
  • Wendy is not accustomed to the company of strangers at nighttime (such as when the moon is full).
  • I will entertain "yes" or "no" questions. This may be one of those riddles where you first need to narrow down the situation; there may be more to Wendy than meets the eye: What is special about Wendy?
