Hello Komal

For taking admission in nit patna with ECE branch ; you should secure atleast 20000 rank for the safe position .

So check your rank in the result and you can see last year's cut off for nit patna and have a reference :

But I think your rank is not upto the mark because with this percentile your rank us around 40-50 thousand.

Good luck.
