Riddles, brain puzzles and mathematical problems

The mail guy because he is lying.

Pages NO2 and NO3 are essentially in the same paper (but opposite sides) and therefore they cannot hold anything between.

The other riddle was solved by JAP already

---

In a game show there are three logicians A,B,C. The presenter of the show whispers a (natural) number greater than 0 in the ear of each logician. Then he tells them that the sum of the numbers is 14 and then he asks them if anyone knows all the numbers:

A: I don't know, but I am absolutely sure that the other two have different numbers.
B: I don't know, but I was absolutely sure that everyone had different numbers even before I listened to A.

Then C announces that he knows the number of all three.

How did he figure it out and what were the numbers?
