For example, University of Delhi(DU) provides admission to various courses on merit basis on the best four marks scored in 12th class. Similarly there are other institutions as well who provide merit based admission.

You didn't mentioned the name of the course nor the name of the college in which you want to take admission. In general for professional courses you have to appear for entrances and for some college offering academic courses can also have entrances but in most colleges for BA/BSc/BCOM course you can take admission on the basis of 12th merit.
