The worlds first riddle!

What number when multiplied against itself will result in a number which includes the numbers (in forward order, and then descending in order from the 9? (i.e., to get the number: 12,345,678,987,654,321) (sorry if I asked this before)

1x1=1
11x11=121
111x111=12321
etc, etc

Why are 1990 dollar bills worth more than 1989 dollar bills

Quote Magnum,"1990 > 1989" One more is enough.

"1x1=1
11x11=121
111x111=12321
etc, etc"

No matter how many times I see this riddle, I always forget the answer.
You have a rope that will reach around the earth (+/- 40,000 km). If you put sticks of 1 meter high around the world and lay the rope on these sticks, how much longer will the rope need to be

Now, whatever the answer, what would it be for 100km or 1000 km in radius.

Here's one for the math wizards: Three companies agree to split the $1,000,000 cost associated with a toxic waste cleanup, as follows: 1) Company A agrees to pay four times the amount of Company B; 2) Company C agrees to pay one-fourth the sum of the amounts paid by Companies A and B. How much will each company pay

"One third of six and two thirds of eleven make seven." Explain why this statement is correct.

A traveller comes to a fork in the road which leads to two villages. In one village the people always tell lies, and in the other village the people always tell the truth.
The traveller needs to conduct business in the village where everyone tells the truth. A man from one of the villages is standing in the middle of the fork, but there is no indication of which village he is from. The traveller approaches the man and asks him one question. From the villager's answer, he knows which road to follow.

What did the traveller ask

A magician is standing on a concrete floor holding a raw egg with his hand outstretched. Without the aid of any objects, he is able to drop the egg two feet without breaking it's shell. How does he do it?

Wow! I saw part of a British BBC TV programme called ?'Mind Games'
The five questions set had all been posted on the Riddles forum.
Oxen and plough. Aircraft and damage. Divide time. Sequence and next number.
So, well done people, keep posting your on TV.


Now for something completely different. Looks easy, that is until you try.


How many Noncongruent triangles can be drawn on a 3 by 3 grid by connecting the dots

Basically, the term congruent means that two or more things are the exact same size and shape.

A traveller comes to a fork in the road which leads to two villages. In one village the people always tell lies, and in the other village the people always tell the truth.
The traveller needs to conduct business in the village where everyone tells the truth. A man from one of the villages is standing in the middle of the fork, but there is no indication of which village he is from. The traveller approaches the man and asks him one question. From the villager's answer, he knows which road to follow.

What did the traveller ask

in wich way would the other person lead me if i asked him the road?

if the man always lie, then you would lead to the wrong way because the truthteller would you in the right direction, if you asked this to the truthteller he would also lead you in the wrong way because the liar would.
so after posing this question you must take the other road

A magician is standing on a concrete floor holding a raw egg with his hand outstretched. Without the aid of any objects, he is able to drop the egg two feet without breaking it's shell. How does he do it?

the fall the egg takes i much higher than 2 feet, so the first 2 feet the egg does not break but evantually it does

What did the traveller ask
"in which way would the other person lead me if I asked him the road?"

There is no ?'other person'. Therefore, he could not ask that question. Even if there were, they could both be from the same village. :wink:

the fall the egg takes much higher than 2 feet, so the first 2 feet the egg does not break but eventually it does.


A bank customer had $100 in his account. He then made 6 withdrawals, totaling $100. He kept a record of these withdrawals, and the balance remaining in the account, as follows:

$ Value of Withdrawals.............. $ Value of Balance remaining
$50......................................... $50
25........................................... 25
10........................................... 15
8............................................. 7
5............................................. 2
2............................................. 0
___ ___
$100....................................... $99


When he added up the columns as above, he assumed that he still had $1 in the bank. Was he right

well then you can just slightly change magnum's question

"If I would ask person from other village, which road is correct, what would be his answer?"

Explanation is same

Point taken, I can not debate against the combined forces of MyO and Magnum. Not while they are shareing the ?'virtual toffee apple' prize.
(Can you see the sequence) post.

I give you a different answer for your consideration.

The traveler asked "which road goes to your village". He would then take the road the villager pointed to because a truthful person would point toward the truthful village, and the liar would also point to the truthful village since he is a liar and, therefore, could not point to his own village.

If you are so good at puzzles answer me this;

Here is a rather simple question with a "yes" or "no" answer. It just happens to be phrased in a roundabout way, but that shouldn't disturb you if you find a way to reduce it to it's fundamentals: :wink:

"If the puzzle you solved before you solved the puzzle you solved after you solved the puzzle you solved before you solved this one, was harder than the puzzle you solved after you solved the puzzle you solved before you solved this one, was the puzzle you solved before you solved this one harder than this one?"

Yes or no

that's really cool answer Try

Puzzle - No
(actually I am just guessing, I haven't try to actually understand it )

"Puzzle - No
(actually I am just guessing, I haven't try to actually understand it"

Well you have a 50-50 chance of being right.

I don't think anyone will fully understand it. I do not even understand the answers to these questions.

An old fashioned bike wheel has 21 spokes. How many spaces are between the spokes

hm...."G"?



lots of things - violent removal of his scalp for example...




um....long road??




21

hm...."G"?

"lots of things - violent removal of his scalp for example..." Whilst not wrong, the answer is much simpler.

"um....long road??" Whilst one could not argue with your logic the answer is in the air.

"21 " Spot on.


This is difficult and maybe open to different answers.

My first is in endurance but not in health
my second is in richer but never in wealth
my third is in beggarwood but not in oak
my fourth is in neighbour but not in folk
my fifth is like a ring, going where it came
and my sixth is the second, exactly the same.

What am I

this is a total mis interpretation of the statistics, it's just coincidence that the difference is 1, if he withdrew immediately 100 dollars he could have seen there was nothing left, but if he withdrew a hundred times 1 dollar he had great depts

Do we have any bank managers out there? Or, is Magnum right?

Another one that I do not understand. Genius wanted.

Tom was exploring an old temple in the lost desert when he came across an old door set into the stone wall. He knew that he had to get the door open, but how? Inside were riches beyond his imagination. Wiping off the dust he read the word 'MRN'. How odd, thought Tom, must be in some other language. He read further... the next word seemed to say 'MLMP'. Wow, what an odd language, must have been spoken by an incredibly odd people. Wiping off the last of the dust, Tom read the last word - 'MRNM'. Maybe ancient peoples always spoke with their mouth full!

How does he get the door to open
HINT: He has to say something.

Said the young girl, "My name is Elizabeth, and my
Grandmother has the same name. I am named after her.

"These riddles are too difficult to answer. I post them for reference purposes for future generations!"

Ten years from now Tim will be twice as old as Jane was when Mary was nine times as old as Tim.

Eight years ago, Mary was half as old as Jane will be when Jane is one year older than Tim will be at the time when Mary will be five times as old as Tim will be two years from now.

When Tim was one year old, Mary was three years older than Tim will be when Jane is three times as old as Mary was six years before the time when Jane was half as old as Tim will be when Mary will be ten years older than Mary was when Jane was one-third as old as Tim will be when Mary will be three times as old as she was when Jane was born.

How old are they now



All the items in the first list share a particular attribute. The second list is of some items lacking the attribute.

With: battery, key, yeast, bookmark
w/out: stapler, match, Rubik's cube, pill bottle

With: Rubik's cube, chess set, electrical wiring, compass needle
w/out: clock, rope, tic-tac-toe, pencil sharpener

With: koosh, small intestine, Yorkshire Terrier, Christmas Tree
w/out: toothbrush, oak chair, soccer ball, icicle

Points to realize:
1. There may be exceptions to any item on the list, for instance a particular clock may share the properties of the 'with' list of problem two, BUT MOST ORDINARY clocks do not. All the properties apply the vast majority of the the items mentioned. Extraordinary exceptions should be ignored.
2. Pay the most attention to the 'with' list. The 'without' list is only present to eliminate various 'stupid' answers.

something to do with alphabetical order because she doe not have to have the same LAST name as her grandmother

Magnum, "something to do with alphabetical order because she doe not have to have the same LAST name as her grandmother"

I think you have it. The ?'clue' is in the question (just) named.
Bank manager is also right. You are the man!


How can I solve logic puzzles (e.g., as published by Dell) automatically

Which Box Contains the Gold? Two boxes are labelled "A" and "B". A sign on box A says "The sign on box B is true and the gold is in box A". A sign on box B says "The sign on box A is false and the gold is in box A".

Assuming there is gold in one of the boxes, which box contains the gold


You are a biochemist, working with a 12-slot centrifuge. This is a gadget that has 12 equally spaced slots around a central axis, in which you can place chemical samples you want centrifuged. When the machine is turned on, the samples whirl around the central axis and do their thing. To ensure that the samples are evenly mixed, they must be distributed in the 12 slots such that the centrifuge is balanced evenly. For example, if you wanted to mix 4 samples, you could place them in slots 12, 3, 6 and 9 (assuming the slots are numbered from 1 to 12 like a clock).

Problem: Can you use the centrifuge to mix 5 samples


One for that guy who likes boats. :wink:

A dysfunctional family has to cross a river. On one side of the river are a mother and father, two daughters, and two sons. Also present are the family maid and a dog. There is a boat only big enough to hold two people (counting the dog as one person). Only the adults are capable of operating the boat. Everyone has to get to the other side, without anything bad happening.

Now, some difficulties: if the dog is left with anyone and the maid is not there to control him, he will bite. The father cannot be left with any of the daughters when the mother is not there because she does not trust him. Likewise, the mother cannot be trusted alone with either of the sons when the father is not there. And remember: only an adult can operate the boat and the boat cannot drive itself.

How can they do it Or can they

Well, guy who likes boats was ALMOST tricked with this one. I almost finished proving why this can't be solved when, in last second, I thought of possible step 2. Sometimes you just overlook things I guess
However, later it was piece of cake

However, your gold boxes riddle really cannot be solved with information given

I agree with Mr Mou that answer cannot be deduced
