QUESTION PAPER PATTERN
The
question paper will consist of only objective type questions.
Candidates have to mark the correct choice by darkening
the appropriate bubble
against each question on an Objective
Response Sheet (ORS). There will be negative
marking for wrong answers.
The deduction for each wrong answer will be 25%
of the allotted marks.
MAIN PAPERS
(i) Group I: Question Numbers 1 to
20 (20 questions) will carry one mark each (sub total 20 marks).
(ii) Group II: Question Numbers 21
to 75 (55 questions) will carry two marks each (sub total 110 marks). Out
of these, Q.71 to Q.75 may be common data
based
questions.
(iii) Group III: Question Numbers 76
to 85 (10 questions) will carry two marks each (sub total 20 marks). These
questions are called linked answer
questions. These 10 questions comprise five pairs of questions (76 &
77, 78 & 79, etc.). The solution to the second question of each pair (e.g.
Q.77) will be linked to the correct answer to the first one (e.g. Q.76) in
the pair.
-
Each question will have four choices for the answer.
Only one choice is correct.
-
Wrong answers carry 25%
negative marks. In Q.1 to Q.20,
0.25 mark will be deducted for each wrong answer and in Q.21 to
Q.76, Q.78, Q.80, Q.82 and Q.84, 0.5
mark will be deducted for each wrong answer. If the first question in the
linked pair is wrong, then the second question in the pair will not be
evaluated. However, there is no negative marking for the linked answer
questions in Q.77, Q.79, Q.81, Q.83 and Q.85.
-
Papers bearing the code AE, AG, CE, CH, CS, EC, EE, IN, IT, ME, MN, MT,
PI, TF will contain questions on Engineering Mathematics to the extent of
20 to 25 marks.
-
The multiple choice objective test questions can be of the following
type:
(i) Each choice containing a single
stand-alone statement/phrase/data.
Example
Q. The state of an ideal gas is changed from (T1,
P1) to (T2,
P2) in a constant volume process.
To calculate the change in enthalpy,
Dh, ALL of the
following properties/variables are required.
(A) Cv, P1,
P2
(B) Cp, T1,
T2
(C) Cp, T1,
T2, P1,
P2
(D) Cv, P1,
P2, T1,
T2
(ii) Each choice containing a combination
of option codes.
The question may be accompanied by four options P, Q, R, S and the choices
may be a combination of these options. The candidate has to choose the
right combination as the correct answer.
Example
Q. The following list of options P, Q, R and S are some of the important
considerations in the design of a shell and tube heat exchanger.
P: square pitch permits the use of more tubes in a given shell diameter
Q: the tube side clearance should not be less than one fourth of the tube
diameter
R: baffle spacing is not greater
than the diameter of the shell or less than one fifth of the shell
diameter.
S: the pressure drop on the tube side is less than 10 psi
(A) P, Q and R (B) Q, R and S (C) R, S and P (D) P, Q, R and S
(iii) Assertion[a]/Reason[r] type
with the choices stating if [a]/[r] are True/False and/or stating if [r] is
correct/incorrect reasoning of [a]
Example
Q.
Assertion [a]: Bernoulli’s equation can be applied along the
central streamline in a steady
laminar fully-developed flow through a straight circular pipe.
Reason [r]: The shear stress is zero at the centre-line for the above
flow.
(A) Both [a] and [r] are true and [r] is the correct reason for [a]
(B) Both [a] and [r] are true but [r] is not the correct reason for [a]
(C) Both [a] and [r] are false
(D) [a] is false but [r] is true
(iv) Match items: Match all items in
Group 1 with correct options from those given in Group 2 and choose the
correct set of combinations from the choices E, F, G and H.
Example
Q. Group 1 contains some CPU scheduling algorithms and Group 2 contains
some applications. Match entries in Group 1 to entries in Group 2.
Group 1 Group 2
P- Gang Scheduling 1- Guaranteed Scheduling
Q- Rate Monotonic Scheduling 2- Real-time Scheduling
R- Fair Share Scheduling 3- Thread Scheduling
(A) P-3; Q-2; R-1 (B) P-1; Q-2; R-3
(C) P-2; Q-3; R-1 (D) P-1; Q-3; R-2
(v) Common data based questions:
Multiple questions may be linked to a common problem data, passage and the
like. Two or three questions can be formed from the given common problem
data. Each question is independent and its solution obtainable from the
above problem data/passage directly. (Answer of the previous question is
not required to solve the next question). Each question under this group
will carry two marks.
Example
Common Data for Questions 74 and 75:
Let X and Y be jointly distributed random variables such that the
conditional distribution of Y, given X=x, is uniform on the interval
(x-1,x+1). Suppose E(X)=1 and Var(X)=5/3.
First question using common data
Q.74 The mean of the random variable Y is
(A) 1/2 (B) 1 (C) 3/2 (D) 2
Second question using common data
Q.75 The variance of the random variable Y is
(A) 1/2 (B) 2/3 (C) 1 (D) 2
(vi) Linked answer questions: These
questions are of problem solving type. A problem statement is followed by
two questions based on the problem statement. The two questions are
designed such that the solution to the second question depends upon the
answer to the first one. In other words, the first answer is an
intermediate step in working out the second answer. Each question in such
‘linked answer questions’ will carry two marks.
Example
Statement for Linked Answer Questions 80 and 81:
Consider a machine with a byte addressable main memory of 216 bytes. Assume
that a direct mapped data cache consisting of 32 lines of 64 bytes each is
used in the system. A 50x50 two dimensional array of bytes is stored in the
main memory starting from memory location 1100H. Assume that the data cache
is initially empty. The complete array is accessed twice. Assume that the
contents of the data cache do not change in between the two accesses.
First question of the pair
Q.80 How many data cache misses will occur in total?
(A) 48 (B) 50 (C) 56 (D) 59
Second question of the pair
Q.81 Which of the following lines of the data cache will be replaced by new
blocks in accessing the array for the second time?
(A) line 4 to line 11 (B) line 4 to line 12
(C) line 0 to line 7 (D) line 0 to line 8
