Jesta: Picks an envelope, and asks the king to open it for him. Dunno if it’s right…

Try this one:

A prisoner has 100 balls. 50 white and 50 black. He has 2 jars. The guard is going to take 1 ball from a jar with closed eyes. If it’s white, he’s set free. If it’s black, he’s going to be in jail for the rest of his life. How should he mix the balls to get the highest chance of a white ball? (The jars are shaked, so he can’t put the white balls on top).

This thread truly makes my head hurt. I have a hate-love relationship with riddles.

Here is a few guesses to the recent riddles:

Jabbervock - I can’t even think of a witty comment for an answer to “Why is a raven like a writing-desk?” … Does it have anything to do with Edger Allen Poe?

ulrik_tr - Does the prisoner separate the colors into the separate jars, then give the “white jar” to the guard to guess from? ???

Jesta - I wouldn’t open the envelopes.

… this is getting easy.

kmcdonald - I … uh … … Hm? … I’m suppose to be genius ya know? but I hate word math problems. Is it 3 feet? The water doesn’t rise from the deck of the boat, but it does for the dock. … unless the boat has a hole.

traumgänger - Please tell me how and why the three men guessed the correct answer at the same time. kmcdonald’s explaination confused me … it doesn’t take much. and I really can’t guess why they all answered at once.

Here is an oldie but goodie. I use to know the answer to this riddle, but I always forget it. It baffles me even to this day. Let me try to recall how it goes:

[i]“This Missing Dollar”
3 salesmen stay in a hotel. They order a pizza which totals $30, so they decide to split the cost. Each man pays $10. The pizzaboy arrives late and quickly makes the transaction. Before the pizzaboy gets to far, he relizes he did not give the men their $5 discount for being late. He returns 5 $1 bills to the three men. The three men were pleased with his honesty and gave him a $2 tip, and kept and split the remaining $3 dollars. Which means the 3 men only paid $9’s each for the pizza.
9 times 3 = $27

Dreamaddict: No, he mixes the balls, and put both jars side-by-side.
The guard can’t see which jar he reaches his hand in, and the prisoner can’t say what jar the guard should take from.

He Picks One And Tears It Up And Asks The King To Open The Other one.

I Got a new one for ya

A Window Cleaner was cleaning windows on the fifteenth floor of a sky scraper when he sipped and fell. He only suffered minor bruising. How was this possible when he is not wearing a safty harness and nothing slowed his fall?

A raven is like a desk??? Hmm… perhaps because nobody likes working on it? g

If this is really a math problem, I think it doesn´t matter how the balls are mixed…
Sooooo… The prisoner puts 25 white balls in each jar,and throws the black balls away?

That´s what I really love&hate about riddles: You never know wether the answer is something logical, something totally absurd or something that is too obvious to be concidered

@DreamAddict
Sorry,I don´t know if I can explain it any better, kmcdonal was perfectly right.But I´ll try:

3 White flags
1 Black flag

->2 Possbilities:

1.Two have a white and one has a black
Two of the prisoners see the black flag, so they immediately say “Mine is a white” since there isn´t a black one left.

2.Everyone has a white
Nobody says anything, since they all see 2 white flags.BUT if any had a black flag, the other two would know that theirs is white (see possibilitie 1).So, nobody can have a black one.

A man is on a journey, he wants to find the hidden land.At some point, the pass splits into two (left and right).At each side is a guard, and in the middle is a sign that says:

“Only the smartest people shall find our hidden land.You can ask our guards for the way, but you can only ask ONE question.One of the guards is always lying, the other one always says the truth.”

ulrik_tr : if there has to be 50 balls in each jar, the probabilety of picking a white ball is not dependent on how many white balls there are in each jar.

Best one:
“Think of words ending in -GRY. Angry and hungry are two of them. There are only three words in the English language. What is the third word? The word is something that everyone uses every day. If you have listened carefully, I have already told you what it is.”
Very hard

ulrik_tr : the prisoner puts all the white balls in one jar and the black in the other.

ok if you realy like math try this one

There is 5 men and a monkey on an island, they have been gathering coconuts all day and have fallen asleep.
The first man wakes up and decides to hide his share of the nuts, he devides the nuts in to 5 equal shares and gives the monkey the nut left over. after hidding his share he goes back to sleep.
After a while the second man wakes up and does as the first man. devides the nuts in to 5 equal shares ,gives the nut left over to the monkey and hides his share.
one after one tha last 3 men does as above, each time giving one nut to the monkey.
what is the smallest number of coconuts the men could have gathered ?.
(what if there is 101 men on the island?)
