Dear Ralla Sowmya,

The percentile system in JEE Mains has been included in 2019 so no earlier data is present for the percentile system. For rank, it depends whether you are asking for Planning or Architecture and to which category you belong. Here is the last year cutoff to give you an idea of rank required for Planning-

Category           Opening Rank               Closing Rank

General              415                                1314

Schedule Caste   113                                 313

Schedule Tribe    81                                    231

General PwD       3                                      3

OBC Pwd            20                                   20

OBC                 340                                  653

Here is the last year cutoff to give you an idea of rank required for Architecture-

Category        Opening Rank               Closing Rank

General              183                              870

Schedule Caste   19                                 93

Hope this helps you.
