Hii Ranu,
89% must your over all percentage. For admission in Delhi university you must calculate the percentage of your top 4  subjects. You should have English as your compulsory subject in class 12th with a minimum of 55 marks in it.
For a girl Bharti college, Satyawati College and Mata sundri college are good options in 89 % or above.
You can also go for Sir Aurbindo college.
I hope this answer will help.
All the best for your future!!
