Hello Ritish,
To get into DU the minimum percentage to qualify should be above 94%. Since enough have scored 91.25% it is difficult to get admission. Alternatively, you can try taking the DU entrance examination and take admission.
Also try our new college predictor link below :

In top colleges like SRCC, Hindu College, St. Stephens, Ramjas College, Hansraj etc,  chances are low as these colleges have cut offs in the 96%-99% range. In colleges like Acharya Narendra Dev College, Aryabhatta College, Deshbandhu college, Dr. Bhimrao Ambedkar College, Dyal Singh College, Motilal Nehru College, P. G. D. A. V college, Rajdhani college, Shivaji College, Shyam Lal College, Sri Aurobindo College (evening). 
Do keep an eye on cut off of each rounds, in the later rounds the cut off goes lower. 

I could not understand your point about merit base. If you could explain it in the comments below, I can help you better.

Hope this helped. Good luck.
