hello sunil sir i got an AIR of 415 and score of 505 in GATE 2016 what are the options available to me

Hello Raj,
Congrats for your score. You should be getting calls from IIT Madras, Kanpur, Guwahati. If you apply for departments othr than biotech then you may expect calls from other IITs as well. Assuming your percentile is well above 90, I suggest you as well to try for PhD at NUS.

All the best
