there are 2 people named jack and john. both of them have split personalities. jack in his normal state always tells the truth and in his altered state always tells lies, john in his normal state always tells a lie and in his altered state always tells the truth.

Suppose you were to meet just 1 of them, what simple yes or no question could you ask to find out what his name is?

Originally posted by Dance Master MC you don't know which state their in right now

It doesn't matter what state they're in right now. John will always answer "yes" because he will tell the truth if he is in an altered state and lie if he is not. Jack will do the opposite, therefore always answering "no".

i have trouble opening doors, sometimes running into them as i grab...so advanced topics like no and opposite states are "tuff"ðŸ˜‰
