Hello Hema.
There is no concept of Pass marks in CLAT.  Based on the marks of each candidate a merit list is prepared and ranks given to each. Admissions are done based on the ranks. Cut off ranks are released each year aftet the process of counselling is over.
Here is a list of NLUs and their respective cut offs for the general category for admission through CLAT in the previous year. You can expect a similar range of cut off this year  too.
