Ankit, yes with these marks you can get admission in MIT and even in some of the NITs.
But in case with this good score in 12th and JEE score you fail to get a good college of your choice, you can get you a seat in some of the best private universities that are offering admissions both on the basis of JEE score and 12th marks.
Some of the good private universities are also offering good scholarships on the above criteria.

you are eligible but there is less chances to get admission there

yes you can apply d.pharma first 2 year thn you will be transferred to b.pharm 2 year overall 5 yrs complete.

there are very few good ones in maharashtra.apart from IIT and nit. You can try for symbiosis.

Their are 17 nlus in the county all except nlu delhi requires CLAT point and delhi required AILET points. for any nlu you will need atleast 45% in class 12th form any stream and CLAT or AILET points. The cut offs may may vary with different nlus and the difficulty level of exam.

Dear Ankita,
With 71% marks in 12th , B.com Hons in any college of DU is almost not possible reason being cutoffs goes so high even a average college comes with cut offs of 80%+ .but you can still try because if seat remains vacant then cutoffs will go till 13th or 14th and then it may be possible that you can get admission.
But my advise is you should also apply for B.com as well because cut offs of B.Com remains average and then in 2nd year after scoring good if college permits you can switch to B.com Hons.
All the very best
