Hey Rohit,

Among these two i would suggest you to go with RS.Agarwal.

It is a very nice book with great explanations on all topics also it has solve examples on all these topics. Lots of question of various kinds along with those which have appeared in the past. 

If one is able to solve the questions from RS.Agarwal he sure can score great in boards plus it will also help in upcoming future ie with completion purpose.

Thank you.

Hi Rohit. I would suggest that if a person is an average student then he/she should go throug NCERT first. And then switch to RD Sharma And RS Aggarwal.Moreover, R.D.Sharma and RS Aggarwal are best for maths preparation. And after that one should solve all the questions that came in the question paper since last 10years. And last 10years' solved question papers are available in books by many authors, one of them is Arihant. 

i hope this information has helped you:)
