I bought this book from online store i.e https://amazon.in at Rs 225.
Coming to the point, this book will teach you only tricks about each and every topic. But as it says, its a practice book for banking job aspirants unfortunately it lacks adequate number of practice question. There are about 20-25 questions at the end of each topic which is very low in compare to other practice books which is not enough for banking job aspirants. Moreover, the difficulty standards of question are not at par with ibps exams. Personally, in my opinion this book is waste of time and money.
