Hey Shankar

this time the rank will be based upon the percentile .

and 360/360 marks means 100 percentage and 100 percentile.

but if 346 is highest in other slot than he will also have the same percentile but different percentage than in this case the rank will be decided by the maths percentile followed by physics and than chemistry an dif by chance all are same than younger student will secure better rank.

percentile makes all the paper equal.( because if one slot difficult marks of every one is less and if other slotb is easy than marks are high).

and if 346marks student is in same slot as 360 marks his percentage remainsame but percentile decrease.

I hope , i solve your doubt
