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
