Hey,

It would be difficult for you to get a seat in Delhi technological University with 81% for bba and that too belonging to general category. 

With a score of 90 above you may be partially assured to get  admissions may be till 3rd cutoffs .

The first list expected to open at 96 -97 % and closes at 94-93%.

You may check the  official website of the college for more information regarding the previous years cutoffs and expect to fall in the same range. 

Hope this helps.
