#### ESE / GATE / PSUs Numerical Ability, Theory & self practice questions

The study material for Numerical Ability is thoroughly revised this year to meet the requirements of all categories of students. It consists of

(i) Brief synopsis covering the entire syllabus

(ii) Worked out examples, concept wise

(iii) Practice questions

The students are advised to go through the theory duly understanding the worked out examples to the extent possible and practice the questions, By doing so, the students will get familiarized with some of the concepts and can really enjoy the lecture in the class. Also, the students can interact with the faculty in a better way.

After attending the classes and understanding the typical questions explained by the professors, the students will be in a position to solve these questions in work book. However, for verifying the correctness, Hints/solutions are also given wherever required, The student is advised to struggle to get the solution for the problems in the work book by self analysis and not to refer the solution first.

Thanks to all professors who extended their services in the preparation of this booklet.

It is believed that this volume is also a valuable aid to the students appearing for competitive exams like ESE, ISRO, State and Central Commissions and other PSUs.

#### GATE – 2019 Computer Science & Information Technology Previous GATE Questions with solutions

The style, Quality and concept of the solutions for previous GATE Questions of Computer science and Information Technology, will encourage the reader to learn & understand the concept thoroughly and answer the question without any difficulty or tension.

The student must go through the solutions for conventional questions asked prior to 2003, to bridge up the concepts by solving conventional questions this will facilitate the students to answer the numerical type questions, and also Common data and linked questions, easily.

The student is advised to solve the problems without referring the solutions. The student has to analyse the given questions carefully, identify the concept on which the question is framed, recall the relevant equations, find out the desired answer, verify the answer with the final key such as (a), (b), (c), (d), then go through the hints to clarify his answer. This will help to face numerical questions, better. The student is advised to have a standard text book ready for reference to strengthen the related concepts, if necessary. The student is advised not to write the solution steps in the space around the question. By doing so, he lose an opportunity of effective revision.

In 2018, for the first time, one single set of question paper is prepared to conduct the online examination for all candidates who are appearing for the exam. In GATE-18 , ( CSIT) around 37% of question paper is asked in the form of numerical type. It is expected that this will be continue even in 2019. Framing of questions in the forth coming examinations may turn difficult. Because, examiners need to prepare a single set of question paper, covering wide range of topics from the whole syllabus, due to which it turns difficult for students to make any predictions in the examination. Students are strongly advised to cover whole of the syllabus without leaving any topic in any subject while their preparation.

It is believed that this book is a valuable aid to the student’s appearing for competitive exams like ISRO and other PSUs. This book can also be used by fresh teachers in Engineering in improving their Concepts.
