"If you give me your photo, you'll give me a kiss!"

If yes, it's easy.
If no, that means the statement is false and if she gives him a photo, he doesn't get a kiss - but she does so she has to give him a kiss (I know this can be argued against) - this also means: if she doesn't give him a photo, she gives him a kiss.



she could just say that's a lie. no photo. no kiss. i understand where your logic is coming from but it's easy to see that it doesn't work.

here's how i think you came to your conclusion: the girl thinks, "well he's lying, so i don't have to give him my photo. but now that i haven't given him the photo, what he said could be true." yes, it could be true, but isn't necessarily. it could still just be false. since the girl decides whether it's false or not (in the solution you gave, this would be the case) then she decides whether to kiss you or not. no guarantee.

I think this one works:

"I will receive a kiss from you or I will not get a photo."

If she gives him a photo then the statement would be a lie and so she can't give him the photo.
If she does not give him the photo then it will be true and she has to give him the photo.

The only way out is to give him the kiss which makes it a true statement and thus he must also get the photo. Since the "or" conditional is true if either part is true then this is consistant.

Sound right?

Slim Lover - Back to the Logic Problems
Something to relax. A slim young man asked a girl on a date:
"I say something. If it is truthful, will you give me your photo?"
"Yes," replied miss.
"And if it is a lie, do not give me your photograph. Would you promise that?"
The girl agreed. Then the chap said such a sentence, that after a little while of thinking she realized, that if she wanted to honor her promise, she wouldn't have to give him a photo but a kiss.
What would you say (if you were him) to be kissed and so on?


Spoiler for Solution




Wait does that one work?

If she gives him a kiss the the statement is a lie, and so she can't give him the photo or the kiss.
If she does'nt give him the kiss or or doesn't give him the photo, or both, then the statement is true,but it wold contradict itself and so she could not give him a photo or a kiss.

What you seem to have here is a statement that makes resolving the issue impossible, but not one which forces her to give a kiss.

OOOPS, my bad, I see why it works now. I think my solution works too though, and mine is nice becauase it guarantees the photo as well. <!-- s:) --><!-- s:) -->

Better yet, to allow her to give you both a kiss AND her photograph (if she wishes to give you the picture):
Spoiler for ...

If you want to force the matter and get both a kiss and her photograph, you could do so:
