Riddle me this.....

[drblac0]

Then no thanks, gonna let someone else answer this one. Don't feel like trying all the permutations with a calculator right now.

 

[Uka Uka]

Okay... This was probably the hardest one ive done but when posed to my friend who does calculus he got the number to 381654729 after 15minutes or so of calculating... I would ask him how but the writing he did was amazing

Next pl0x

More questions!!!

:O



The number is 381654729

The number is 381654729 because
381654729 / 9 = 42406081
38165472 / 8 = 477068
3816547 / 7 = 545221
381654 / 6 = 63609
38165 / 5 = 7633
3816 / 4 = 954
381 / 3 = 127
38 / 2 = 19
3 / 1 = 3

The Oompa Loompas from Willy Wonka and the Chocolate Factory (the old one with Gene Wilder)??? They're from a movie... :lol:

And would this be the thread to throw out some logic puzzles? Like:

"There are three chests. One chest contains only gold coins, one contains only silver coins, and one contains only bronze coins - but all three are mislabelled. One label says "gold", another says "bronze", and the last says "gold or silver". How many chests do you have to open to find out the true contents of each chest?"

I love logic puzzles and riddles.

Zero. Weigh them! (Assumption is that they are all filled to the top of identical chests)

Or, open Gold or Silver. because it is mislabelled, it MUST contain bronze. From that, you have Silver and Gold in chests labelled Gold and Bronze. Silver will be in Gold chest, and Gold will be in bronze chest.

The pillars of the top bridge are above the arc of the bottom!
My physics knowledge tells me the bridge would collapse O_O

Is that the design on a real 5 euro note?

The strange thing is that the aquaduct is very badly designed from a engineering point of view. Half of the pillars of the second floor stay above the weakest point of the bottom bows. That doesn't make the construction stronger.

For political reasons, the objects drawn on euro banknotes do also not exist in reality.

Bob and John form a team together. Bob is as old as John will be when Bob is twice as old as John was when Bob was half as old as the sum of their current ages. John is as old as Bob was when John was half as old as he will become over ten years.

How old are Bob and John?

bob is 40 and john is 30 :confused1:

 

[RurouniKenshin]

Wait no, John is 40 and Bob is 30? OMG IM SO CONFUSED STUPID MATH :angry:

You're correct if you combine your two answers. You don't have scales, so you can't weigh them, but you don't have to open any chests (using the logic in your second answer). :thumbup1:

bob is 40 and john is 30 :confused1:

And I think this is right and Bob is older.

 

[Uka Uka]

Yep... not really a difficult one... just gotta look at it and work out what you need to do... As people said Jogn is 30 and Bob is 40

One of the first ones we did after our exams... Isnt too hard... First one to get it gets a cookie

Here's one:

There are three types of people: soldiers (who always tell the truth), spies (who always lie) and engineers (who sometimes lie and sometimes tell the truth).

You encounter three individuals (A, B, and C) who are personally unknown to you - but you DO know that at least one is a soldier. They make the following statements:

A says: B is a spy
B says: A is a soldier
C says: Either A or B is telling the truth

Which one is definitely a soldier? And can we tell what the other two are?
