Hello Prakash,

Thanks for contacting Careers360.

With this much percentile, I doubt that you will qualify for the JEE Advanced. 

But don't loose hope. The National Test Agency NTA will declare the combined result of both the JEE Mains exam (1st which was held in January and 2nd which is going to be held in April) after the declaration of result of 2nd exam i.e. after April 30. You have to wait as of now.

Meanwhile prepare for the other engineering exams.

Hope this helps.

Good luck!!
