The syllabus is not covered in this book. This book contains only a few examples of questions.Even though it contains some shortcut method but not provided for all problems.My point of view is that see this book in internet and kindly note the shortcut methods
I'd recommend this book to anyone who intends to undertake preparation for IBPS-CWE (Clerical/PO), LIC-AAO, SSC-CGL, etc. It's concise, comprehensive, and error-free. Its compact size implies that serious aspirants can revise the book at least thrice before appearing for the exam.
However, this book alone is not sufficient for CAT/XAT. If you are seriously looking at taking the CAT/XAT then you may use this book as a starter or an 'appetizer'.
