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

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.

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
