As the the board criteria for getting admission on the basis of JEE Main B.Arch/B.Planning, the candidate must have secured an aggregate of at least 50% in his/her respective board exams. So, as you have scored 60%, you satisfy this criteria to get admission.

Now, to get admission on the basis of these two exams, you will have to apply for JoSAA counselling, and then on the basis of your rank, you will get admission into some of the NITs.

Hope it helps.
