Take all the balls and roll them off from the top off slope. The one that is slightly farther or closer is the ball with the odd weight. Take the weight of that ball and compare it to the first one. Take the weight of another ball and compare it to that. If the odd ball is > than the other two balls then it's heavier. If it is <, vice versa. Uh, I don't think this is a trick question where you get to use other things outside the scale. If it was a trick question you would just take balls off the scale one by one each time you used it lol. Ya but everytime u take a ball off the scale that counts as 1 weigh=p
+ Show Spoiler +Damnit how do u use 3 measures? I keep having to use 4.

Two coins cannot appear together on the same weighing because if the fake one is one of them we wont know which it is. So numbering the coins from 1 to 12 we have the following weighings:
1) 1,4,7,10 x 3,6,9,12 2) 3,6,9,10 x 2,5,8,12 3) 3,4,8,12 x 2,6,7,11 Please use spoilers. + Show Spoiler +But yes, it is correct. Though my answer was a one page long algorithm.

If you then turn the fan on it will distribute evenly.
First set all buttons to off, then put some sand in the box. Then turn buttons 'red' and 'blue' on for a while before turning them off again. Now put some more sand in the box and let button 'red' be on for a while before turning it off again. Finally, turn button 'green' to on.
When opening the box his will result in different outcomes: Sand cone on top of a flat layer of sand=>Blue Sand cone=>Yellow Flat sand and fan turned off=>Red Flat sand and fan turned on=>Green

Sorry I forgot about the spoilers... fixed it Zerg-Legend you have the right idea, I'm not gonna say yours doesn't work, because it is logical, but there is one that does not rely on sand cones (would be kinda hard to tell if there is a sand cone on top of flat layer of sand or not)

Don't know#1. You are wearing a blindfold and thick gloves. An infinite number of quarters are laid out before you on a table of infinite area. Someone tells you that 20 of these quarters are tails and the rest are heads. He says that if you can split the quarters into 2 piles where the number of tails quarters is the same in both piles, then you win all of the quarters. You are allowed to move the quarters and to flip them over, but you can never tell what state a quarter is currently in (the blindfold prevents you from seeing, and the gloves prevent you from feeling which side is heads or tails). How do you partition the quarters so that you can win them all? http://en.wikipedia.org/wiki/Chicken-and-egg_problemShow nested quote + Definitions
The dilemma can be interpreted differently using different definitions of a chicken or an egg. In biology, the term egg is biologically ambiguous and the theory of punctuated equilibrium, for example, does not support a clear division between a chicken and the closest ancestors of that chicken. Both of those factors tend to contribute to the circular nature of the question (causing problems similar to either a hasty generalization or a fallacy of definition). Below are a few different definitions that could be assumed and their logical outcomes.[6]
If the egg is not necessarily of any specific type:
Then it could be said that the egg came first, because other animals had been laying eggs long before chickens existed, such as the dinosaurs. In biology, egg is used as a general term in this way.
*If only an egg that will hatch into a chicken can be considered a chicken egg:
Then a re-consideration of the original question suggests: Some animal other than a chicken laid the first chicken egg which contained the first chicken. In this case the chicken egg came before the chicken. In reality, many scientific theories suggest that this would not have been a simple event. For example, the theory of punctuated equilibrium theorizes that the actual speciation of an organism from its ancestral species is usually the result of many mutations combined with new geographical surroundings, called cladogenesis.
If only an egg laid by a chicken can be considered a chicken egg:
Then a re-consideration of the original question suggests: The first chicken (which hatched from a non-chicken egg) laid the first chicken egg. In this case the chicken came before the chicken egg. Again, this would not necessarily be a straightforward event.

You have 12 balls. They are all coloured differently to help you tell them apart. 11 of these have the same weight, 1 is either slightly heavier or slightly lighter than the rest. Can you, with the help of 3 weightings with a basic balance scale, find out which ball that has a unique weight and whether it's heavier or lighter than the rest?
+ Show Spoiler + I know one method of solving this, but I need to know whether the 1 ball is either heavier OR lighter. T_T

The MBC Game Hero team decided to go on a trip to the USA. Light decided to bring his laptop to practice with him. All the other players were jealous that he could practice while they couldn't. One day, his laptop went missing while he slept.
1. Jaehoon claims that he was busy hooking up with girls last night. 2. Shark says that he never even saw the laptop. 3. Pusan says he saw Sea take the laptop. 4. Sea says he was out last night on a one night stand with a girl he met, and that Pusan is lying 5. Saint says Shark was in Light's room at 3AM last night.
Any of the players could be telling a lie, or could be telling the truth. Who stole Light's laptop?

In preparation for the annual trip he decides to leave at 6 in the morning so as to make the 12 hour trip to the top before the sun sets. Because the trail is long and steep the monk takes many breaks and travels at a varying pace. Finally, he makes it to the top and spends his week in peace and harmony with nature. At the end of the week of meditating, the monk leaves the mountaintop at 9 in the morning and makes his way down the trail, also at a varying pace and with many breaks. This time, however, he makes the trip in only 9 hours.
Prove that the monk was at the exact same point on the trail at the exact same time of day on his way up and down the trail.
Intuitive proof:+ Show Spoiler + Imagine that the monk has an identical twin who starts climbing the mountain exactly like he did on the way up exactly one week after. At 9am when the monk starts making his way down, his twin is somewhere along the route going up. Obviously, they're going to meet up briefly at one point - and that's the time/place we're looking for.
More mathematical proof:+ Show Spoiler +Let f(x) = height on the way up, defined for x in [6am to 6pm] Let g(x) = height on the way down, defined for x in [9am to 6pm] Assume f(9am) < height of the mountain (i.e. he didn't get to the top in 3 hours)
Let h(x) = f(x) - g(x) defined for x in [9am to 6pm]. h(9am) < 0, h(6pm) > 0... so by the IVT (f, g, and h are clearly continuous functions) there must be some point t where h(t) = 0.
