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

• The question paper will be for a total of 150 marks divided into three groups:

(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
