Dear Navneet Kumar,

Yes , as far as your marks in intermediate are concerned, you are eligible. But that will not be enough. To get into Panjab University for B.A LLB, you need to take the exam conducted by the Panjab University itself. The admission will be solely based on their entrance test. So, you need to score good marks in that test. The exam is going to be conducted in June. Applications have already begun. So make haste and apply.

You can also attempt CLAT which is an all India level entrance test to get into NLUs. 

Hope my answer helped.
