Since your marks are less than 75% so you cannot get into NITs.

for SGSITS:

For you getting admission into SGSITS is also difficult as your percentile is very low. But alternatively you can get admission if you have applied for Madhya Pradesh Pre- Engineering Test (MP-PET).  Minimum eligibility is atleast 45% marks in aggregate of Physics , Chemistry and Mathematics. 

IITs:

For getting into IITs you need to crack JEE Advance with a good score. Now, JEE Advanced requires 75%  marks for GENERAL and OBC and 65% for SC, ST & PwD in class 12th examination. So, it will depend on your category and your JEE Mains rank.

But there are many options available with you, you can try for some other college. 

If you have time you can drop one year and appear next year, then you will be able to score much better and surely will get some good college. Many students go for this option because in long journey of life that one year will not matter much but ofcourse your college will. 

It's completely upto you, choose according to your convenience.

Best of Luck.
