A rich Mathematician had two sons:Ben and Charlie . The rich mathematician dies and leaves a will with the lawyer. The lawyer goes to both sons and gives them each one positive integer (both of which could be equal or not). He says to them that their numbers multiply to either 8 or 16. Without asking each other the value of number, the one that figures out other's number wins. The two sons start talking:
Ben: I have no clue which number you have
Charlie: Same here
Ben: You will have to give me a hint.
Charlie: Same here
Ben figures out Charlie number and wins the rich fortunes. What number does Charlie have?
