 PREFACE

There is no better way to get into SSC-JE in an effortless manner than to get into the minds of the examiner/
commission. And, the route to it is reverse engineering the previous years’ questions while understanding the
psychological requirements of learning. What if, in doing so, you not only memorise but also acquire the ability
to project upon the probabilities of the upcoming exam.

As you dive into the revised and updated edition of the book ‘IES Master Previous Year Topic-wise Objective
Detailed Solutions with Theory’ carrying 55 previous years question paper sets, you will start feeling the pulse
of the exam whereby which in turn will help you to develop the feel of subjects. The previous years’ questions
decoded in a Question-Answer format not only give you ample amount of relevant theory, but an extra theory
along with reasoning for other given options.

So, what might appear to other students as disorder, randomness, and wide coverage, becomes order for you
as you work through topic-wise solutions. While delving into the knowledge base, the numbers dance to your
fingers, and the weights assigned to the subjects fit in like a jigsaw puzzle. From here on, you know what to
read, where to read, and how to read.

This masterpiece from IES Master’s Research & Development team ensures that your level of preparedness
matches exactly to that required in the actual SSC-JE exam. Thus far, and no further, the book leaves no stone
unturned in its easy-to-understand language, optimized with fonts and layout that your eyes will surely relish.

 HOW TO GET THE MOST OUT OF THIS BOOK

To get the most out of any book in the most effortless and effective manner, one needs to move ahead in a strategic
manner rather than just wrestling with the content. How a book is read is the biggest determining factor in getting
the most out of any book. Therefore, to help the readers of this book understand its value, we are going to present
hereby a multi-step process that needs to be followed.
Before going into the details about the process, first of all let us understand the structure of this book’s content.
The book includes questions from previous year SSC-JE question papers. The questions are arranged in a topic-
wise manner, and each question has a detailed solution followed by a crux theory related to that particular
question’s topic. A good amount of research has gone into preparing this crux theory as previous years’ question
papers of SSC-JE, State PSCs, and other engineering exams have been comprehensively analysed in a topic-wise
manner. The crux theory has been prepared in such a comprehensive manner that the probability of questions
coming in the forthcoming SSC-JE, State PSCs or other engineering exams from that particular topic becomes
very high.
Now let’s see how the worth of reading this book can be realised in an effective manner. To start with, one need
to read in one go any particular topic-related question, its detailed solution, and the related crux theory. Memorise
the crux theory of that topic before jumping on to the next topic question. As the questions in the book have been
arranged in a topic-wise manner, memorising the theory along with detailed solution will facilitate covering any
particular topic in the most efficient as well as effective manner.
Thus, by reading this book in such a selective and targeted manner, one will cover the entire exam syllabus well
before time leaving no stone unturned.
Our main objective behind bringing out this book is that you as a reader benefit the most from reading it. Hope
by implementing the above-discussed strategy, you achieve success in fulfilling your dream of clearing SSC-JE,
State PSCs or other engineering exams.

All the best!!!

PAPER-I

General Intelligence & Reasoning

The Syllabus for General Intelligence would include questions of both verbal and non-verbal type. The test may
include questions on analogies, similarities, differences, space visualization, problem solving, analysis, judgement,
decision making, visual memory, discrimination, observation, relationship concepts, arithmetical reasoning, verbal
and figure classification, arithmetical number series etc. The test will also include questions designed to test the
candidate’s abilities to deal with abstract ideas and symbols and their relationships, arithmetical computations and
other analytical functions.

General Awareness
Questions will be aimed at testing the candidate’s general awareness of the environment around him/her and its
application to society. Questions will also be designed to test knowledge of current events and of such matters of
everyday observations and experience in their scientific aspect as may be expected of any educated person. The
test will also include questions relating to India and its neighbouring countries especially pertaining to History,
Culture, Geography, Economic Scene, General Polity and Scientific Research, etc. These questions will be such
that they do not require a special study of any discipline.
