Hello Swetabh, Good Evening. You have not mention Category in your question. but here i'll share you cut off marks for the all categories.

General                 150-160

OBC                        120-130

SC                            130-140

ST                            125-135

These are the expected cut off and for student convenience, these expectations are made on the basis of some last year cut offs. so as per these marks , if you fall under other category , rather than General, It has good enough chances for you to get into next stage of NTSE.

I hope it will help you more.

Thanks.
