Dear aspirant,

Percentile depends on several factors like number of students appeared, toughness of question paper etc. There's a simple formula to calculate the Percentile depending on marks.

Percentile = (No.of students having raw score less/ equal to 71/Total no. of student attempted the exam) *100

Depending on these data your approx percentile would be around 88 and rank would be in between 41000-47000.

Hope it would help
