Puzzle 1)

At each bridge is a troll who demands ½ of all of your cakes as the price to pass. However, this troll, being a nice troll, feels bad and gives you back 1 of the cakes that he took.

Puzzle 2)
Jennifer and Jose live in different sections of their town but go to the same school. Jennifer left for school ten minutes before Jose and they met in the park. When they met, who was closer to school? (Yes, it is possible to answer this puzzle!)
They are equidistant since they meet in the same place.
Puzzle 3) An apple costs half a dollar while a pear costs a dollar. Bob at first bought an apple, then he tought: "I already
paid half a dollar, and I have an apple that is also worth half a dollar. So if I give teh apple to the shopkeeper, , he would overall receive a dollar from me. That should be enough to get me a pear." Is Bob right?
No, if Bob were right then the apple and the pear cost the same amount. He is mistakenly counting his apple twice which is why he thinks he can exchange for a pair that is worth double the apple.
Puzzle 4)
2 fathers and and 2 sons ate 3 eggs for breakfast, each eating exactly one egg. How could that be?
There are three people --a grandfather, a father, and a grandson. Therefore, the father is both a son (of the grandfather) and a father (of the grandon).

The puzzles below are not necessary math related but they are so great that I thought I'd include them.
A king decided to replace on of his ministers withut causing too hard feelings. He summoned the minister and asked him to choose one of two folded notes. The king explained that one of the notes says "You are fired" and the other states "You stay." However, the minister found out from a trusted spy that both notes actually say "You are fired." What can the minister do to save his post?
The minister can do something along the lines of
acting like he's too worried to actually read the note that will determine his fate, then saying, "II choose this note " as he grabs and eats that note.
Then the minister says, "Now please tell me what the remaining note says so I can know which fate I chose." (which of course is the OPPOSITE of the note remainig in the king's hands)
