You will learn how to ask this in Marwari. Asking this to someone who speaks Marwari obviously shows that he/she is from Rajasthan. But you see Rajasthani people are spread all over the world.
This question too is asked in 2 forms.
One in a respectful way and the other in an informal way.
Where are you from?
Translation:
Respectful:
Aap katta ra ho?
Informal:
To ask him: Tu katta ro hai?
To ask her: Tu katta ri hai?
