Another Logic Puzzle
Three perfect logicians are each given a number stuck to their forehead. They are told that all three numbers are distinct positive integers such that two of them add to the third.
Logician A looks at B and C and says "I do not know what my number is."
Logician B looks at A and C and says "I do not know what my number is."
Logician C looks at A and B and says "Then my number must be 50".
Logician A and B then both say, "Ah ha, my number must be _____", where "____" is different for the two logicians (obviously).
1) How did C figure out his number?
2) What are A and B's numbers?
3) How did they figure out their numbers?
