GATE 2012 Question Types
Multiple Choice Questions
Multiple choice questions in all papers and sections will contain four answers, of which only one is correct. The types of questions in a paper may be based on following logic:
(i) Recall:
These are based on facts, principles, formulae or laws of the discipline. The candidate is expected to be able to obtain the answer either from his/her memory of the subject or at most from a one-line computation.
Example
Q. During machining maximum heat is produced
(A) in flank face (B) in rake face
(C) in shear zone (D) due to friction between chip and tool.
(ii) Comprehension:
These questions will test the candidate's understanding of the basics of his/her field, by requiring him/her to draw simple conclusions from fundamental ideas.
Example
Q. A DC motor requires a starter in order
(A) to develop a starting torque
(B) to compensate for auxiliary field ampere turns
(C) to limit armature current at starting
(D) to provide regenerative braking
(iii) Application:
In these questions, the candidate is expected to apply his/her knowledge either through computation or by logical reasoning.
Example:
Q. The sequent depth ratio of a hydraulic jump in a rectangular channel is 16.48. The Froude number at the beginning of the jump is:
(A) 10.0 (B) 5.0
(C) 12.0 (D) 8.0
(iv) Analysis and Synthesis:
These can be linked questions, where the answer to the first question of the pair is required in order to answer its successor. Or these can be common data questions, in which two questions share the same data but can be solved independently of one another.
Common data questions
Example
Common Data, for instance, Questions 48 and 49 in main paper:
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.48 The mean of the random variable Y is
(A) 1/2 (B) 1 (C) 3/2 (D) 2
Second question using common data:
First question of the pair:
Q.52 The value of K which will cause sustained oscillations in the closed loop system is
Second question of the pair:
Q.53 The frequency of sustained oscillations is
The questions based on the above four logics may be a mix of single stand alone statement / phrase / data type questions, combination of option codes type questions or match items types questions.

Multiple Choice Questions
Multiple choice questions in all papers and sections will contain four answers, of which only one is correct. The types of questions in a paper may be based on following logic:
(i) Recall:
These are based on facts, principles, formulae or laws of the discipline. The candidate is expected to be able to obtain the answer either from his/her memory of the subject or at most from a one-line computation.
Example
Q. During machining maximum heat is produced
(A) in flank face (B) in rake face
(C) in shear zone (D) due to friction between chip and tool.
(ii) Comprehension:
These questions will test the candidate's understanding of the basics of his/her field, by requiring him/her to draw simple conclusions from fundamental ideas.
Example
Q. A DC motor requires a starter in order
(A) to develop a starting torque
(B) to compensate for auxiliary field ampere turns
(C) to limit armature current at starting
(D) to provide regenerative braking
(iii) Application:
In these questions, the candidate is expected to apply his/her knowledge either through computation or by logical reasoning.
Example:
Q. The sequent depth ratio of a hydraulic jump in a rectangular channel is 16.48. The Froude number at the beginning of the jump is:
(A) 10.0 (B) 5.0
(C) 12.0 (D) 8.0
(iv) Analysis and Synthesis:
These can be linked questions, where the answer to the first question of the pair is required in order to answer its successor. Or these can be common data questions, in which two questions share the same data but can be solved independently of one another.
-------------------------------
Common data questions
Multiple questions may be linked to a common data problem, passage and the like. Two or three questions can be formed from the given common data problem. 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 instance, Questions 48 and 49 in main paper:
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)=
