In today’s competitive world, quantitative aptitude and reasoning play a prominent role in almost all competitive examinations and job recruitment exams. Keeping its importance in mind, this book is designed to familiarize the aspirants with basic mathematical and reasoning concepts. It enables them to apply to a range of quantitative and reasoning problems.
The text is organized in two parts Quantitative Aptitude (Part I) and Reasoning (Part II). The separate sections are devoted to verbal and nonverbal reasoning. It sharpens the ability to apply analytical and logical thinking while gathering and analysing information, designing and testing solutions to problems, and formulating plans.
The main objective of this book is to guide the students to solve the problems within the stipulated time and that too with the higher degree of accuracy. Each chapter contains numerous worked-out examples and practice exercises. The questions range from purely numeric calculations to problems of arithmetic reasoning, graph and table reading, percentage analysis and quantitative analysis.
This book is intended for the students appearing for quantitative aptitude and reasoning test conducted in various competitive examinations such as civil services, common admission test (CAT), Management Aptitude Test (MAT), staff selection commission (SSC), combined defence services (CDS), National Defence Academy (NDA), LIC Assistant Administrative Officer (AAO), bank clerical, bank PO, income tax and central excise exams.
