Hello Abhishek!

You may find the answers of R.D. Sharma's subjective type questions in PDF version online. But PDF of solutions for its objective type questions are probably unavailable on the internet. You will have to purchase its hard-copy from the market or borrow the same from someone. And practicing directly from the book even helps you better to improve the mistakes and hence your overall performance.

Although, you can once try any of the sites I have mentioned below -
