You have 10 chests of gold bars in front of you. Each chest contains 10 gold bars. One of these chests contains defective bars that all weigh 10.1 kg, rather than the standard 10kg.

You have a weighing scale, but you are only allowed to use it once and you can only read the weight on the scale once.

Qn: How do you find out which chest of gold bars is defective?

Call up my brother, ask him to swing by with a scale and weigh 1 bar in each chest and tell me which chest had the defective bars!
Next!

This is an old one. They are actually chocolate bars.

Take one gold bar from the first chest, two from the second, three from the third, etc. and place them all on the scale. The number of tenths of kilograms the total mass exceeds 550 kg is the number of the chest that contains the "defective" bars (though I don't know how gold bars can be defective by containing more gold.)

Here's a puzzle I thought of… a farmer digs 60 pits in the ground in a big circle.

If he chooses an empty pit, drops an apple seed in it, and drops an apple seed in a pit immediately adjacent to it, and then chooses another empty pit, drops an apple seed in it, and drops an apple seed in a pit immediately adjacent, and repeats this process, he is able easily to place apple seeds in all of the pits without placing more than one seed in any one pit.

If he chooses an empty pit, drops an apple seed in it, and drops an apple seed in a pit two spaces away, chooses another empty pit, &c., and repeats this process, he is also able to place apple seeds in all of the pits without placing more than one seed in any pit.

He finds, similarly, that he is able to do this by following the same proceedure, only spacing the pairs three spaces apart. (Boy, this farmer sure seems to have a lot of free time on his hands!)

However, by spacing the the pairs four spaces apart, he is unable to place apple seeds in all the pits without placing more than one seed in any pit, no matter which way he does it.

For how many other spacings, under 60 (a full rotation), is this feat impossible. Why?

^ Here's a more difficult one: why is it that despite Tagutcow's good looks and vast intellect can't he get a date?

Are you hitting on Tagut, Neo? Because you better not be. I will be so pissed at you if you are.

Sadly, I fear even Christopher Langan himself would fold like a house of cards before a mystery of that magnitude.

Connemara, GQgeek, and Thomas are sitting on a fence. Piobaire walks by holding a plate of sausage. Who is left sitting on the fence?
