Need a plan immediately ( 16YO from india )

I live in India and I really need a way to support myself without my abusive family. I will be running away after completing 10th grade so that I have a higher chance of getting a job. I plan on studying from an open school after that. I'm somewhat gifted in mathematics and physics, and I will try to get into university with a scholarship.
Basically I need to arrange for these things so that I can run away-
\ a place to live(I have no idea how much rent will cost, please give me an idea)*
\ a job to pay for rent , food etc.. (please suggest some which will let me earn enough, remember i am*
only going to be10th passed at the time)
\ I should be able to arrange for money (~20-30k rupees) to sustain myself for first 2-3 months*

please tell me what should I plan about, especially about jobs and accommodation
also what other documents should I bring other than my Aadhaar card and birth certificate?
If anyone has experience please clarify
