Hye Manideep,

I am a student of ITM Business School, there is no such cut off mark for entrance. They will conduct their own tests, Group discussions and Personal Interviews, other than entrance tests like MAT, CAT etc. So there is no need to worry about cut off marks. Just have your graduation percentage above 50%, that would be enough to get you through. 

As far as Munjal University is concerned they will ask for a SOP, Statement of Purpose, that have to explain why you want to do your MBA and why in Munjal University. They will shortlist the candidates from those SOP's for interview and group discussion. And there will be one Case Analysis Test conducted by the University itself for the shortlisted candidates.
