Two fathers and Two sons are walking down the street, they find $3 on the ground. Each man pockets $1.

How can this be?

Hehe, you can also apply this with catching fish. ^^

I'll post this one separetly as it's quite long.

Now for Einstein's riddle. Einstein said that 98% of the world's population would not be able to solve it. I want to see how FAST everyone can solve this as it is pretty taxing! Please don't just look the answer up on the web and say "I did it in 10 mins" etc... Be honest and say what time you did it in (if you were able to solve it that is!) For those who already know the answer, please don't spoil :P. I did this in around 30 minutes but I did get VERY LUCKY. Good luck!

• There are 5 houses that are each a different colour.
• There is a person of a different nationality in each house.
• The 5 owners drink a certain drink. They each smoke a certain brand of cigarettes and also have a certain pet. No owner has the same pet, smokes the same brand of cigarettes nor drinks the same drink.
• The question is. “Who has the fish?”

TIP: Writing stuff down is highly recommended!

CLUES

1. The British man lives in the red house.
2. The Swedish man has a dog for a pet.
3. The Danish man drinks tea.
4. The green house is to the left of the white house.
5. The owner of the green house drinks coffee.
6. The person that smokes Pall Mall has a bird.
7. The owner of the yellow house smokes Dunhill.
8. The person that lives in the middle house drinks milk.
9. The Norwegian lives in the first house.
10. The person that smokes Blend, lives next to the one that has a cat.
11. The person that has a horse lives next to the one that smokes Dunhill.
12. The one that smokes Bluemaster drinks beer.
13. The German smokes Prince.
14. The Norwegian lives next to a blue house.
15. The person that smokes Blend, has a neighbour that drinks water.



98% of the world's population would either lose themselves in the complexity of the problem, or after some time come to the answer that the German has the fish.

The remaining 2% would quickly read through the given facts and come to the conclusion that a fish never is mentioned. The fifth animal, which is owned by the German, could really be anything. The answer that I believe Einstein sought is that we don't even know if anyone has the fish.

Those who've come to the conclusion that the German has the fish has build their work upon the, unmentioned (and hence false?), premise that someone must have the fish.

Illusion, I'd say it's pretty implied that the fish is one of the pets. To say otherwise seems like one is just trying to weasel his way out of actually doing the problem.

iLLusioN.ReW: correct! I guess that one wasn't too difficult.

Here's my next riddle:

You are an archaeologist that has just unearthed a long-sought triplet of ancient treasure chests. One chest is plated with silver, one with gold, and one with bronze. According to legend, one of the three chests is filled with great treasure, whereas the other two chests both house man-eating pythons that can rip your head off. Faced with a dilemma, you then notice that there are inscriptions on the chests:

Silver Chest: Treasure is in this Chest.

Gold Chest: Treasure not in this Chest.

Bronze Chest: Treasure is not in the Gold Chest.

You know that at least one of the inscriptions is true, and at least one of the inscriptions is false. Which chest do you open?

I solved Einstein in ~30 minutes but... i clicked accidentally on spoiler so i was solving the riddle while knowing the answer... It is not that hard, so i think that i would be able to do it in similar time without knowing the answer but i will never know...

you have 20 coin machines, each of which produce the same kind of coin. you know how much a coin is supposed to weigh. one of the machines is defective, in that every coin it produces weighs 1 ounce less than it is supposed to. you also have an electronic weighing machine. how can you determine which of the 20 machines is defective with only one weighing? (by one use, we mean you put a bunch of stuff on the machine and read a number, and that's it -- you not allowed to accumulate weight onto the machine and watch the numbers ascend, because that's just like multiple weighings). you are allowed to crank out as many coins from each machine as you like.

Good job =)

If you were to put a coin into an empty bottle and then insert a cork in the bottle's opening, how could you remove the coin without taking out the cork or breaking the bottle?

You and your arch rival are competing for the same girl. After years of battling, you both decide to settle it by tossing a coin.

Your rival produces a coin, but you don't happen to have one on you. You are certain that the coin your rival has produced is loaded, ie. it will come up with heads more than 50% of the time on average.

How do you arrange a fair contest, based purely on chance and not skill, by flipping this coin?

Variation: (COIN BIASING) You and your rival are competing for the same girl, and decide to settle it with a coin toss. Your rival has known the girl longer than you have, so you agree that it is fair for him to have a chance of winning equal to P, where P > 0.5. However, you only have a fair coin. How can you conduct this contest such that the biased probability is manifested? What is the average number of coin flips needed to determine a winner?
