Is it right to say "How about you?"

[Abraaocoutinho]

Someone asks me the question "how old are you?" and answer "I'm 22 y.o.". Is it right to say "How about you?" to return the same question to him/her?

Hi,

Yes, that would be all right. You could simply say: And you?

'How about ...' is often used to ask a more general question about what the other person thinks, feels, wants to do and so on.

Question: I'd like to go swimming. How about you?
