In a message originally to All, atrium!sysop asked for:
# Logic puzzles such as those posed by Dell's Official Pencil Puzzles and
# Word Games. You know, those puzzles that seem to appear on those
# intelligence or Mensa quizzes.
Here's one I got from Dr. Peter Ross here:
*** The Mr S and Mr P Problem, by David Warren
There are two numbers M and N such that 1 < M & N < 100. Mr S is told
their sum S and Mr P is told their product P. The following dialogue
takes place:
Mr P: I don't know the numbers.
Mr S: I knew you didn't know them; I don't know them either.
Mr P: Now I know the numbers!
Mr S: Now I know them too!
Question: What are the numbers?
