Hello Mansi Mittal !
I am here for helping you...
As a research so I got that Delhi University is going to announce 7th merit list in this week or maybe in the next week so you should wait some days more.
for knowing more about Delhi university important dates you can refer below link:

I want to clarify you that on the above link the dates are little bit disturbed so you should consider 5 to 10 days more by including in current dates on the above link.
I hope it will be beneficial for you....
