Best ResponseYou've already chosen the best response.0I have no idea how (2, 3) or (99, 98) are answers. Am I missing something? I think I've heard this sorta riddle before but I don't remember it. My guess is that if one of them had 1 or 100 then one of them would know the other person's number. So any pair of consecutive numbers between (2,3) and (98,99) make sense to me as possibilities.

Best ResponseYou've already chosen the best response.3If qwerty has 2, then lenny must be having either 1 or 3 It is clear to qwerty that lenny is not having 1 when lenny said he doesn't know the other number. So qwerty concludes that lenny must be having 3.. .

Best ResponseYou've already chosen the best response.0Ahhh ok I understand your first two answers now, but what about (3,4) and (98,97) ?

Best ResponseYou've already chosen the best response.3exact same reasoning : If qwerty has 3, then lenny must be having either 2 or 4 Lenny knows that qwety is not having 1 or 100 because qwerty first revealed that he doesn't know the number. So if Lenny has 2, lenny would have known that the other number is 3 at this point.
