Hello anushka soni,
Firstly, it is not possible to predict the total number of merit list for npat 2020 (bba/b.com) that is to be released. Wait for this. As no one knows one about the total number of lists available or appearing candidates.
I hope you get my point.
I hope this helps you out. If there is anything else that I can help you with, then please let me know.
Till then, all the very best. Stay home and stay safe.
