Hey Aastha.

The cut-off for the 2016 was 211/640 for general category.

As the written examination carries 75% of weightage in your final selection one should try to score more than the cut-off marks. The high scorers in exam can rest assured of a convert even if they moderately screw-up their GD/PI . 

There can only be predictions as of now. I have given you the cut off of 2016 which could help you determine the expectes cut off.

Hope this helps you. 

All the best.
