sir,i got 7492 can i get in old iit,s

I'm afraid you can't. Look don't keep the aim of just getting into IIT with whatever branch. Every branch doesn't have same scope. I suggest you to go for NITs via AIEEE instead of opting for Eml or newer IITs. Top few NITs stand above in ranking than newer IITs. Moreover, most of them haven't got any infrastructure of there own which will make you feel like an ordinary engineering college. So better will be you go for NITs. NIT warangal and Tiruchirapally are far batter than newer IITs.
