"The son whose camel comes in second in a race from here to Baghdad shall inherit my entire fortune," the will read. The two sons started to race at full speed but gradually slowed down and stopped, not knowing what to do. After several days the two sons were moving at such a slow pace that it appeared neither would ever reach Baghdad. Not knowing what to do they, knocked on the door of a shack they had come across. Inside lived a wise man. The two sons told the wise man of their troubles and showed him the will's instructions. After studying the document for several minutes, the wise man looked up and uttered two words.

11. Can you place five identical, round coins so that each one of them touches each other one at the same time?

12. You want to find out how quickly your friend rides from home to work on his bicycle. However, you don't have a vehicle, so he is faster than you. You cannot be both at the starting point and at the finishing point of the trip, and you don't trust him enough in this important matter. You and your friend both have stopwatches. How can you reliably measure the time in which your friend can ride to work?

14. You are in a dungeon. There are only two ways out: door number one and door number two. One door you know leads to freedom. However, behind the other door lurks a ferocious dragon who will tear you to shreds if you open the door. Unfortunately, you don't know which door is which. In the room with you are two robots. One is programmed to answer your questions completely truthfully and the other is programmed to lie to you. Unfortunately, again, you don't know which is which. The ferocious dragon is becoming anxious and any second it will break down whichever door it is behind. If this happens you have no chance of survival. Therefore, you have only enough time for one question. You walk up to one of the two robots. What can you ask it that will allow you to know which door to open?
