I see that you have a good rank in JEE advanced that is 759 and in ews category 40 rank. 

You want to join MNC in IIT Delhi. Now if I see previous year closing rank then I find that your cell is almost double than required rank.

Now as ews has been included first time in JEE. So we don't have any record. So nothing can be said .

Just hope for best .

Thank you.
