Hello Aspirant,
See according to the marks given by you in the question your total percentage comes out to be 84.6% which you have calculated and if we go for percentile rank then it is neither released by CBSE nor it is of any use. Because some entrance exams such as JEE consider the top 20 percentile scorers of any board in case the candidate is unable to secure 75% marks in class 12th.
Hence for admission to different colleges your percentage will be considered or a merit list will be prepared by the competent authorities on the basis of your percentage in class 12th.
I hope this information helps you.
Good Luck!!
