Hello Vishnu,
If we go take into consideration last year’s cut-off marks for JJ College, it is as follows:
•    For UR – PH the cut off was 118
•    For OBC -  PH the cut off was 107
•    For SC –PH the cut off was 107
•    For ST – PH the cut off was 107
I hope by analysing last year’s cut-off marks, you can get an approximate idea, what the cut-off will be this time.
I hope this has solved your query and all the best.
