what is the minimum mark to qualify NIT and IIT

which category? can you elaborate?

SC cotagary ki minimum Mark

The closing ranks generally avry every year depending on number of studenst appeared, difficulty level, previous year cutoff trends.

So difficult to gauge any minimum score, but as per trends the  cutoff to get into newer  NITs is  under rank 40,000 under JEE mains as NITs accept only JEE Mains.hence, suggested score of more than 150+ is safe to be considered for getting newer NITs while for top NITs a minimum of 210+ is must.

Coming to top IITs, the cutoffsare under rank 2000 and with newer IITs the cutoff ranks under 9000, which results into cutoffof 310+ for top IITs and for newer IITs it should be around 185+.

The cut off varies branch, category and home state wise as you have not mentioned the same in detail so it would be better to get 150 or above if you wish to get seat in lower or average NITs and if you want to get admission in top NITs then 230-250 marks should be there. Also, if you talk about IITs then the exam pattern of jee advanced keeps of changing year to year so it is quite difficult to predict but tentatively it would be better to get 60% to get seat in top IITs like IIT Bombay, IIT Delhi etc.
