Preface

It gives me great happiness to introduce this book on Civil Engineering

containing nearly 3200 fully solved multiple choice questions. Though

every candidate has ability to succeed but competitive environment,

quality guidance and good source & references for study certainly

give competitive edge.

Year by year number of competitors are increasing and the variety of questions asked

in examination is widening, under such scenario this book will definitely help students

to enhance their skills required to succeed in competitive exams like IES, GATE, PSUs,

State Engineering Services etc.

While preparing this book utmost care has been taken to cover all the chapters and

variety of concepts which may be asked in the exams. The solutions and answers

provided are upto the closest possible accuracy. The full efforts have been made by

MADE EASY Team to provide error free solutions and explanations.

I must express my thanks to Mr. Prashant Agarwal (IES) who has contributed to bring

this book on time.

I have true desire to serve student community by way of providing good sources of study

and quality guidance. I hope this book will be proved an important tool to succeed in

competitive examinations. Any suggestions from the readers for the improvement of

this book are most welcome.
