Hello buddy, to get admission in IITS/NITS/IIITs you should score 75% in 12th board or you should be in top 20 percentile of your respective board. It's the sum of all subjects.  Your overall percentage should be 75%.

I hope maximum it is only mpc or pcm because now most of the universities are considering that only and when coming to jee even the languages are considered for rank calculation. So once check which university are you applying for and if you are asking generally it will taken as whole marks along with languages.
