For my recruitment examinations I really needed a best book for the preparation of quantitative aptitude paper. I researched a lot and finally found this book from Dr. RS Aggarwal.
Guys, I have gone through almost every topic of this book and I am really impressed by its simple approach and topics it covers.
It is the best book for Quantitative Apti papers and I am recommending it for every aspirants of competitive examinations and freshers for campus recruitments.
The most important sections it covers are Arithmetical ability which contains 35 chapters and Data Interpretation itself contains 4 chapters.
Worth buying it guys.
