Rank in JEE Main Paper 1 can be calculated by the formula:

Rank = (100-percentile)*(No. of students appeared for the examination)/100

As the no. of students appeared for Paper 1 (Jan) are around 869000, your rank will be around 30000. However as the no. of students in April changes, your rank will change according to that.

With this rank, you have less chances of getting a seat through open category, but since you are from OBC category, you have some chances of getting a seat in a NIT/IIIT.
