Hello,

Cutoff depends on lots of factors so it can't be said like this. Here are some factors:-

1. How average candidates have performed in the category
2. How the paper was
3. Total Number of seats are reserved
4. Previous year cutoff value
5. How many candidates has appeared the exam and their interest in different branches..

Previous year the cutoff for OBC was 74.31. For more information, Please visit the webpage and read the article:- https://engineering.careers360.com/articles/jee-main-cutoff

Hope it helps!
