Dear friends, Here, I wish to review about the book quantitative aptitude compiled by R.S.AGGARWALl, This book contains upto 726 pages in seventh edition.First of all, this book covers almost all syllabus/topics of aptitude asking in competitive exams, important formulae.In each topic, there is an basic concept are given in that related topics, Also in each topic, some example questions are given with step by-step solution, And also more objective type questions in each and every topic. Overall view:In this book, there is an formula based traditional solving methods are given.But to face the competitive approach, My suggestion is this book should update the every edition with short cut tricks and tricks to solve questions rapidly
