First Edition : 2018 Typeset at : IES Master Publication, New Delhi-110016 PREFACE Union Public Services Commission (UPSC) in its quest for best engineering minds looks for the very basic pride of an engineer, which it tests through your quantitative and analytical abilities. The profession itself calls for putting you in situations, both human and technical, where things are tied into hundred knots. As an engineer you are expected to think critically, detect systematic themes while analysing data, and achieve thoroughness with accuracy in deriving solutions under challenging circumstances. To test these qualities in an ESE aspirant, in the year 2016, UPSC introduced Engineering Aptitude as a part of the syllabus for common paper of ESE in 2016. With an objective to develop these abilities, IES Master has come up with this Engineering Aptitude book that brings you face-to-face with thousands of problems under various sub- heads such as probability, polynomials, speed-time, work-time, clock and calendar, as well as geometry and measurements that you might encounter as a professional. Covering 171 topics under 25 chapters in 5 units, this book is an effort by IES Master to expose you to the complete theory of ESE syllabus along with previous years questions from UPSC (last 38 years), GATE (last 9 years), and ESE (last 2 years). As you flip through the pages of this book, it captures your imagination with subtleness, and exposes you to more than 1,200 problems, enough to give your pen the required strength to take on any competitive exams including ESE, GATE and PSUs. Under the expert guidance of Mr Kanchan Kumar Thakur (Ex-IES), Mr Puneet Sharma, who has more than 14 years of teaching, has tamed the tornado that will blow you away, with its concept clarity and conciseness. Having gone through it, we hope that as your fingers follow your command, the brain will engineer solutions no matter how difficult the challenge is.
