I am not getting why you want to join NIE Mysore. Better you prepare for NIMCET for few months and clear the competitive exam. Based on your score, you will get prestigious institutes like NIT Trichy, NIT Surathkal, NIT Allahabad, etc.
Otherwise below is the detailed information:
50% Candidate must have passed any recognized BCA / Bachelor degree in Computer Science Engineering or equivalent degree and obtained an aggregate minimum of 50% marks (45% of marks in case of SC, ST and Category-I of Karnataka candidates) taken together in all the subjects in all the years of the Degree Examination from any recognized institute/university. OR Candidate must have passed B.Sc. / B.Com / B.A. with Mathematics at 10 + 2 level or at Graduation level (with additional bridge courses as per the norms of the concerned University) and obtained an aggregate minimum of 50% marks (45% of marks in case of SC, ST and Category-I of Karnataka candidates) taken together in all the subjects in all the years of the Degree Examination from any recognized institute/university. Final year students can also apply on provisional basis

It is all dependent upon your catagory so if you are in lower category like SC, ST then you can join top colleges, but if you have fees issue then also you can apply for loan or scholarship if you are eligible. And if you have no fees issue you can also join colleges like amity, srm institute, mpgi and so many other institutes based on your rank. Go for counselling for best one. Your rank is okay for getting admission into some of the top private colleges of the country. But you will not be able to secure a seat in NIT'S without quota. But with this rank you can get pretty good colleges. It is totally fine to have this rank. Well, if you want you can admission into private colleges that are known for providing good education. And else if you want to join government colleges. Just work hard this year, give the exam next year and there you will be in one of the government colleges.

M.Tech and MBA both have very good career options, it would be an injustice to compare both of them. Both of them have their own perks. You should choose one among them based on your interest and capability. M.Tech gives you more knowledge into technical sector and the ability to think new which can lead to innovation, this helps you very well if you're planning on growing your career towards tech sector. MBA helps you build a good career as well but into a different field I. e. Management jobs, and it helps you if you're planning on getting into Business world. M.Tech is highly reputed in the area of engineering and Technology, whereas MBA is popular in the area of Business Management. You are saying that you've less percentage in your BE, I don't know the reason behind that but if the reason is you are not interested in engineering, then it might be good for you if you don't choose M.Tech which deals with Technology again. You can go for MBA if you're into it. Hope you'll find your interest. All the best Idrees :). .

As told by other people here the cut off ranks for SRM are almost correct and the IBC also get the following problems
But to be honest SRM is not really a great option for B.Tech and here is why that is true:-
As you compare the investment and the return you get after 4 years, they are nowhere near. I mean why would somebody give 16 lakhs to study in SRM knowing that the avg. package is of 3 to 3.5 Lakhs and that too for CSE branch, which is by the way their best branch and all of this statistical data is for Main Campus. I was excited too after I got my result for SRMJEE, it was 1602 rank but after going through all the evidences, I concluded that it won't be a wise decision going in SRM. And for north Indians to bear that type of climate, it will be the worst experience to be honest.
