Question: how to calculate percentage of gate marks?
Answer: P = ( (N- your rank)/ N) x 100 (N- Your rank) indicates the number of candidates who have scored less marks than you. For example, if total number of candidates are 100 and 90 of them have less marks than you P = (09/100)X100 = 0.9×100 = 90 percentile. The candidate has 99.83 percentile.
