Hope you are doing well coming to your question I will say as pattern of jee advance always change from year to year and cutoff of jee advance depends on difficulty level of question .so it is not possible to say how much marks you need but 40 %to 45 % of marks will be safe side .you just need to come under 10K (general category rank) to get admission in IIT.

Hope my answer helped you

Thank you

All the best
