The seven IITs are IIT Kharagpur, IIT Kanpur, IIT Madras, IIT Delhi, IIT Bombay, IIT Guwahati and IIT Roorkee. 

This year, JEE Advanced will be conducted by IIT Roorkee on 27th May.

As for your question, the ranks with respect to marks can vary every year depending on the difficulty of the paper. So, it isn't possible to give accurate information on this. Once the exam is conducted, you can get a proper estimate.
