Dhanush, 

If you have done your class 10 and 12 from Telangana then you will get the home state quota benefits. 

Last year closing rank for different branches was

Technology  8241

Chemical Engineering 5805

 Civil Engineering 4382

 Computer Science and Engineering 804

 Electrical and Electronics Engineering  2185

Electronics and Communication Engineering 1452

Mechanical Engineering 2868

 Metallurgical and Materials Engineering 7264

So you need to get Atleast 200 marks in JEE MAINS. 

Hope it helps.
