Hello Soumyajit, based on your neet marks and considering the trend of last year rank prediction you'll get a rank somewhere around 24,000-26,000. But again, This is not the exact rank which you'll get because the rank depends on other factors like the difficulty of paper compared to last year. But it will be somewhat around this only.

It is difficult to predict your rank as rank could be affected by various factors like number of students appeared for the exam, difficulty level of the paper, highest number scored by the students and previous year data. 

You can predict your rank with the help of neet UG rank predictor who's link I have mentioned below.

But note that your actual rank could differ than this.

Hope it helps.

Thank you
