Hi, dear let me tell that the government used to increase seats in various IIT's, NIT's, IIIT's  and GFTI's  because of increasing no of candidates per year so to balance the pressure of students they increase seats in government institutions every year. But  the seats may vary in different institutions as how much seeats needs to get increase is decided by the particular institution management. Previous year Approx. 4500 seats were increased in combined IIT, NIT, IIIT and GFTI.

Good Luck.
