Beginners book with improvement needed. Review on Objective Arithmetic - RS Agarwal

The RS agarwal book on the objective arithmetic is sure the book for the beginners and not an too tough book but that does not mean it is too easy too be done with as the objective of the book is to make the concepts the basic ones first getting clear so to cope up with the tough level questions and topics on the next level. The book is easily understood and not a complicated one that needs support from others to get the concepts written in it clear as with the solved examples in details it gives all the clear idea about the topics related and the concepts with all the basic questions that goes on to even cover the 30-40% question of the same type exactly in the actual examination. The suggestion would be to surely go for the book but to the author and publisher would be to improve the book according to the day to day changing patters and syllabus.
