why their is hot discussion on this topic, better understand things properly. 15% reserved for SC, 7.5% reserved for ST &, 27.5% of OBC (including all) total will be 49%. now as per population all these counted for nearly 75%, thus remaining 51% seats for 25% population, because once you will be provided with reservation, you never going to apply for a seat without it and this is reality. conclusion the persons making debates on the issue are mostly benifited virtually.
