Hello,

I'll explain you the concept of this percentile and marks ok... 

Marks scored by you multiplied by 100 and divided by the marks scored by the topper this year is your percentile. 

So substituting the given information, 

We get your marks multiplied by 100 divided by 701 = 8.4277656 .

So on calculations your marks will come out as approximately 59 out of 720.

Thank you.
