Dear aspirant,

It is difficult to predict your actual Rank as it depends on a number of factors. You can use the following formula to get an estimate of your JEE Main rank -

100 - your total percentile score is the percentage  of people ahead of you. 869010 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

With your current Percentile it is hard for you to get admission in DTU
