How you been?
Where you been?

how have you been maintaining two cars !
आप दो गाडिया कैसे इस्तेमाल कर रहे हैं । { मेहेंगा जमाना है ना । }

where have you been for the last two months
पिछले दो महीनों मे आप कहा थे (गायब हुये)

have you ever been to the Moon ?
yes, I have been to the moon in my dreams !

As you can figure out from .vaani’s post, “how you been” or “where you been” would be wrong as they are. Correct usage is “How have you been” and “where have you been”.

@.vaani, very good work. Let me add something here:
“How have you been?” is a complete question in itself, it does not need to be a part of another sentence.

@Vinod007 (and .vaani),
You can find examples of that here: http://www.shabdkosh.com/forums/viewthread/767/
