There is something which you can be arrested for attempting but not for successfully completing.

Your job is to measure 45 minutes if you have only two cords and matches to light the cords.

2. Each cord burns from end to end in exactly one hour.

Describe your way of measuring the 45 minutes.

Which city is three-fifths chick two third cat and 50% goat?

Prove that twice of ten is the same as twice of eleven.

The host of a game show offers the guest a choice of three doors. Behind one is an expensive car, but behind the other two are goats.
After you have chosen one door, he reveals one of the other two doors behind which is a goat (he wouldn't reveal a car).

Now he gives you the chance to switch to the other unrevealed door or stay at your initial choice. You will then get what is behind that door.

You cannot hear the goats from behind the doors, or in any way know which door has the prize.

Should you stay, or switch, or doesn't it matter?
