With the shipments came a note from the factory explaining that there was a problem with one of the packaging machines and one of the colors of jellie beans has 1g too much in each of the bags. However, the note did not specify which color was incorrectly packaged. Using a scale in your store, can you figure out which color weighs too much with only a single measurement?
What kind of scale are we talking about here? One that can just directly compare two things to see which is heavier? Or a digital scale with an accurate readout?

He's talking about a digital scale.
Take one bag of blue jelly beans, two green ones, three red ones, four yellow ones, five orange ones, and six purple ones. Say they add up to 2104 g. Now, if all the bags were correctly weighed, it would add up to 2100 g. Because you're 4 g over, there must be 4 overweighted bags, thus they must be the yellow ones.
You've packed 8 boxes of Rubik's Cubes for a local game store. However, there's one cube left on the floor. Because you don't have much tape left, you want to make sure you only open the correct box (it doesn't fit in any of the other boxes). You can't hear anything rattle inside the boxes to determine there's something lacking in one of them. You've got a comparative scale available. Can you determine in just two measurements which box doesn't weigh enough?

Take six and weigh them three and three. If they are the same, then weigh the two you left out and pick the lightest. If not, take whichever three is lighter and weigh two of them. If they are the same, the one you left out is the lightest. If they aren't the same, the lighter one on the scale is the lightest.
Lightest = missing the cube.

Next one.
WARNING: Professor Layton veterans might wanna refrain from spoiling the answer.
You've one match left to use.
You want to turn on your heater, warm up your bath, and turn on the furnace to cook dinner.
Which one should you light first?
RE: Riddles! - TheGoldenGriffin - 05-04-2013 06:12 AM
The furnace so you can use the furnace fire to turn on the heater and warm youe bath?
RE: Riddles! - Gf!sh - 05-04-2013 06:39 AM
Nope.
RE: Riddles! - TheGoldenGriffin - 05-04-2013 06:50 AM
Is the heater the fire type?
Is the furnace the hearth type?
RE: Riddles! - Gf!sh - 05-04-2013 06:55 AM
They all require to be lit manually.
RE: Riddles! - TheQwertiest - 05-04-2013 07:18 AM

Suppose you are headed to the Village of Truthtellers, where everyone always tells the truth. You come to a fork in the road, where one path leads to the Village of Truthtellers, the other leads to the Village of Liars, where everyone always lies, but you don't know which path is which. There is a villager native to one of these villages at the fork, but you don't know which village he hails from, so you can't be sure if he's a liar or a truthteller.
By asking a single question, determine which path leads to the Village of Truthtellers.
