Hello Aspirant,

It would be difficult to tell you the category rank, You may calculate your general rank by using the formula.

100 - your total percentile score is the percentage  of people ahead of you. 874469 are the number of candidates appeared for Jan exam. So rank formula is (100 - your total score) X 869010 /100. If the number of candidates for April exam increased to 1200000 then your final rank shall be (100 - your total score) X 1200000/100

Using the formula
(100 - your total score) X 869010 /100.

Your probable rank will be 30, 936.

With this percentile, You can have the chances to get-

National Institute of Technology Tiruchirappalli- Civil, Chemical, National Institute of Technology Karnataka Surathkal, National Institute of Technology Warangal, National Institute of Technology Rourkela, National Institute of Technology Calicut-ECE, Mechanical.
