Hello Yuvateja,
As EWS is a newly introduced system i dont have much idea about it and not much data is available about it.However considering your PwD reservation roughly i can say that you can easily get into the best NITs(Tiruchirappalli,Waranghal,Rourkela) with a decent branch.
You can use the college predictor to give you an even better idea
