if you really want to be technical.... a well is defined by its brick/concrete foundation. it has solid walls and a floor (for the most part), so you could easily pull it out with enough manpower. with that said, you would still leave the shape and the water behind... but the well itself would be removed. it would just be a watery pit.
PS - i realized the answer had to be something stupid like a hole... didn't know exactly what, so i didn't post.
wow... i know 5 year olds that know the answer to that riddle.
sad.
here is a tough riddle:
You are given 5 bags. There are 10 beads in each of the bags. In four of the bags, the beads each weigh 10 kilograms. In the remaining bag, each bead weighs only 9 kilograms. All the bags and beads look identical. You must find out which bag has the lighter beads. The problem is that all the bags look identical and all the beads look identical. You can use a scale, but it has to be a single-tray scale, not a two-tray balance scale. Also, you may use the scale only once. How can you find out which bag has the lighter beads?
A boy was at a carnival and went to a booth where a man said to the boy, "If I write your exact weight on this piece of paper then you have to give me $50, but if I cannot, I will pay you $50."
The boy looked around and saw no scale so he agrees, thinking no matter what the carny writes he'll just say he weighs more or less.
In the end the boy ended up paying the man $50. How did the man win the bet?
speaking of mental capacity of 5 year-olds... he wrote "your exact weight"
and Tass to yours, I think I have a complicated way, but an easy way would be to dump out the contents of one bag, put it on the scale, and place one bead frmo each bag into the empty bag and see when it jumps differently, but I dont' think thats the answer you want
Place the bags in a row. Take one marble from the first bag, two from the second bag and so on. Use the scales to weigh all the marbles you have taken from the bags. If the number of grams ends in 9, it is the first bag with 9 gram marbles. The total for the other bags will end in 0 since 10s are being added. The single 9 shows up as the rightmost digit in the sum of all the weights. If the number of grams ends in 8, it is the second bag with the 9 gram marbles because 2 times 9 equals 18 and that will be added to the total producing a number ending in 8. A rightmost 7 means it is the third bag with the 9 gram marbles. In each case the rightmost digit reveals which bag contains the 9 gram marbles. My friend asked me this riddle, and I still remember the answer.
Or you could put all 3 on the scale, take one off at a time, and see which one only subtracts 9 from the total weight, for example...
All 3 weigh 49 kilograms.
You take one off, now it weighs 39 kilograms, you know it's not that one.
You take another off, it's now 29 kilograms, you know it's not that one either.
You take another one off, it's now 20 kilograms, since it subtracted 9, then you know it's that sack.
Of course you could debate on whether 5 bags could fit on a single panel scale.
Some random guy decides it's time for his three random sons to get an inheritance. He gives each son 50 dollars and tells them to buy something that would fill a room with it.
The first son returns with $50 worth of feathers, but only manages about 33% of the room. The old guy empties the room and tells his son he's a failure.
The second son returns with $50 worth of hay, but only manages about 50% of the room. The old guy empties the room and tells his son he's a failure.
The third son returns with cash left over and manages to fill the room. The old man commends this son for being intelligent and gives him the house. Please to be explaining this.
