SAMPLE PAPER-2
Sample Questions – Theoretical Computer Science
Unlike in Physics, there is only one paper. The test will focus on the following areas:
Analytical Reasoning and Deduction, Combinatorics, Data Structures and Algorithms,
Discrete Mathematics, Graph Theory, Principles of Programming
In each of these areas, familiarity with the basics (including the necessary simple
mathematics) is assumed and will be tested. There will be questions of both varieties –
some requiring short answers as well as some involving detailed problem solving.
Some text books which may help the candidate prepare for the test are listed below. The
candidate is not expected to read all the books. There is no specified “portion” for the
test; rather, the test is designed to check the applicant’s understanding of foundational
aspects of computing.
Suggested texts:
1. Elements of Discrete Mathematics - C.L. Liu
2. Discrete Mathematical Structures with Applications to Computer Science -
Jean-Paul Tremblay and Ram P. Manohar
3. Compilers: Principles, Techniques and Tools - Alfred V. Aho, Ravi Sethi and
Jefferey D. Ullman
4. Fundamentals of Data Structures - Ellis Horowitz and Sartaj Sahni
5. An Introduction to Data Structures with Applications -
Jean-Paul Tremblay and P.G. Sorenson
6. Fundamentals of Computer Algorithms - Ellis Horowitz, Sartaj Sahni and
S. Rajasekaran
7. The Design and Analysis of Computer Algorithms - Alfred V. Aho, John E. Hopcroft
and Jefferey D. Ullman
8. Introduction to Algorithms - Thomas H. Cormen, Charles E. Leiserson and Ronald L.
Rivest
9. How to Solve it by Computer - R.G. Dromey
10. Programming Languages - Concepts and Constructs, Ravi Sethi
Sample Questions for JEST inTheoretical Computer Science:
1. Select the correct alternative in each of the following:
(a) Let a and b be positive integers such that a > b and a2 - b2 is a prime number.
Then a2 - b2 is equal to
(A) a - b (B) a + b (C) a × b (D) none of the above
(b) When is the following statement true? (A [ B) \ C = A \ C
(A) If ¯ A \ B \ C = _ (B) If A \ B \ C = _ (C) always (D) never
(c) If a fair die (with 6 faces) is cast twice, what is the probability that the two
numbers obtained di_er by 2?
(A) 1/12 (B) 1/6 (C) 2/9 (D) 1/2
(d) T(n) = T(n/2) + 2; T(1) = 1. When n is a power of 2, the correct expression for T(n)
is:
(A) 2(log n + 1) (B) 2 log n (C) log n + 1 (D) 2 log n + 1
2. Consider the following function, defined by a recursive program:
function AP(x,y: integer) returns integer;
if x = 0 then return y+1
else if y = 0 then return AP(x-1,1)
else return AP(x-1, AP(x,y-1))
(a) Show that on all nonnegative arguments x and y, the function AP terminates.
(b) Show that for any x, AP(x, y) > y.
3. How many subsets of even cardinality does an n-element set have ? Justify answer.
4. A tournament is a directed graph in which there is exactly one directed edge between
every pair of vertices. Let Tn be a tournament on n vertices.
(a) Use induction to prove the following statement:
Tn has a directed hamiltonian path (a directed path that visits all vertices).
(b) Describe an algorithm that finds a directed hamiltonian path in a given tournament.
Do not write whole programs; pseudocode, or a simple description of the
steps in the algorithm, will suffice. What is the worst case time complexity of
your algorithm?
5. Describe two different data structures to represent a graph. For each such
representation, specify a simple property about the graph that can be more
efficiently checked in that representation than in the other representation. Indicate
the worst case time required for verifying both of your properties in either
representation.
6. Two gamblers have an argument. The first one claims that if a fair coin is tossed
repeatedly, getting two consecutive heads is very unlikely. The second, naturally,
is denying this. They decide to settle this by an actual trial; if, within n coin
tosses, no two consecutive heads turn up, the first gambler wins.
(a) What value of n should the second gambler insist on to have more than a 50%
chance of winning?
(b) In general, let P(n) denote the probability that two consecutive heads show up
within n trials. Write a recurrence relation for P(n).
(c) Implicit in the second gambler’s stand is the claim that for all sufficiently large n,
there is a good chance of getting two consecutive heads in n trials; i.e. P(n) > 1/2.
In the first part of this question, one such n has been demonstrated. What
happens for larger values of n? Is it true that P(n) only increases with n? Justify
your answer.
7. Consider the following program:
function mu(a,b:integer) returns integer;
var i,y: integer;
begin
---------P----------
i = 0; y = 0;
while (i < a) do
begin --------Q------------
y := y + b ;
i = i + 1
end
return y
end
Write a condition P such that the program terminates, and a condition Q which is
true whenever program execution reaches the place marked Q above.

Sample Questions – Physics
The syllabus for JEST M.Sc level Physics paper is the standard M.Sc Physics syllabus.In particular,
it presumes that the candidates have taken basic courses in Mathematical Physics, Classical Mechanics,
Electromagnetic Theory, Quantum Mechanics, Statistical Mechanics and some special subjects such as
Condensed Matter Physics, Electronics, Nuclear Physics etc.
The Physics question paper will be a multiple-choice question paper only. It will contain questions
of two levels of difficulty. The first level will have 25 “easier” questions carrying 1 mark each. The second
level will have 25 “difficult” questions carrying 3 marks each. Therefore, the test questions will have a total
of 50 questions with 25 from each level, adding to a total maximum marks of 100. 40% questions will be
from B. Sc. Level and 60% questions will be from M. Sc. Level.
