It is a simple and excellent to learn aptitude for beginners written by R.S.Agarwal.
The content of books divided into two parts.1. Arithmetical ability, 2. Data Interpretation.
The specialty of this books is initially starts with simple problems and ends with difficult sums. if we solved all the problems in this book means surely we can archive all the exams and interviews.
we will get interest automatically when we entered in to this book fully. If we get bored means not get any interest. so we have to concentrate some days in this book for getting interest. after some days we will be eager while solving problems. we will get some positive energy while got answers for problems.
we can easily manage timing by solving problems in this book. we can use some tricks to solve easily to manage our time in banking exams.
its having many example questions with answers and some problems with answer to develop our aptitude skills.
I prefer this book to learn aptitude. Its an best book ever for competitive exams.
