I guess this is a basic Paradox in itself and the answer is evident understanding the fact that its a paradox.

"There was a barber in a village, who promised to shave everybody, who does not shave himself (or herself).
Can the barber shave himself and keep the mentioned promise?"

The correc6t answere is that the Barber is a woman. therefore she never needs to shave herself, and she can shave each of the men in the village.

i think that the barber can keep his promise!!! he promises o shave everybody who doesnt shave himself/herself meaning all customers! if we consider the barber as a "customer" then when he wants to shave he goes to the "barber" and get shaved(though he doesnt pay anything!) and the promise is kept!

It's easy: the Barber has shop in the Village but he himself lives in another.
Or it's a traveling barber.

Well, this appears to be a simple English rules question. Because of the location of the commas in this sentence, we could re-word the sentence to read: "There was a barber in a village who does not shave himself (or herself), who promised to shave everybody." Therefore the answer is yes, of course, the barber, who does not shave himself can shave himself and keep the promise to shave everybody.

However, given the nature of the question, I believe the question being asked is " There was a barber in a village, who promised to shave everybody who does not shave himself or herself." In which case the paradox lies in the concept that he promises to shave those people who do not shave themselves. He can, of course, keep this promise. There is nothing in the barber's promise that says he can only shave those people who do not shave themselves. He can shave people who shave themselves too, even himself.

The only way this can be true is if the barber is a women (or otherwise does not need to shave),
or the barber sports a beard
