Informal:
* Kya kar rahe ho? (क्या कर रहे हो?) - This is the most common and general way to ask.
* Kya chal raha hai? (क्या चल रहा है?) - This is a more casual way to ask, literally meaning "what's going on?".
* Kya ho raha hai? (क्या हो रहा है?) - This is similar to the previous option, but slightly more informal.
Formal:
* Aap kya kar rahe hain? (आप क्या कर रहे हैं?) - This is the polite way to ask someone, using the respectful pronoun "aap".
* Kya kar rahe ho ji? (क्या कर रहे हो जी?) - This is a more formal way to ask, adding "ji" at the end for politeness.
Remember:
* Haryanvi is a regional dialect, so there may be variations in pronunciation and vocabulary depending on the specific region.
* It's always a good idea to ask a native speaker for confirmation if you're unsure about the best way to say something.
