Hi Shankar, hope you are doing well, here are the books you need to go through to prepare well for the M.com entrance exam Pune University, for maths you go through Nirali Prakashan's Engineering Mathematics. This book is more than enough to get you with full marks in Mathematics. Other subjects you can refer to any standard books, they don't differ much.

I think it helps you!!!

Keep Smiling:)

Wish you good luck!:)
