Questions (4-7):
The regular mathematics faculty could not teach because of being sick. As a
stop gap arrangement, different visiting
faculty taught different topics on 4 different days in
a week. The scheduled time for class was
7:00 am with maximum permissible delay of 20 minutes. The monsoon made
the city bus schedules
erratic and therefore the classes started on different times on different days.
Mr. Singh didn’t teach on Thursday. Calculus was taught in the class that
started at 7:20 am. Mr. Chatterjee took the class on Wednesday, but he didn’t teach probability. The class on Monday started at 7:00 am, but Mr. Singh didn’t teach
it. Mr. Dutta didn’t teach ratio and proportion. Mr. Banerjee, who didn’t teach
set theory, taught a class that started five minutes later than the class
4. The class on Wednesday started at:
A. 7:05 am and topic was ratio and proportion.
B. 7:20 am and topic was calculus.
C. 7:00 am and topic was calculus.
D. 7:20 am and topic was set theory.
E. 7:05 am and topic was probability.
5. The option which gives the correct teacher- subject combination is:
A. Mr. Chatterjee – ratio and proportion
B. Mr. Banerjee – calculus
C. Mr. Chatterjee – set theory
D. Mr. Singh – calculus
E. Mr. Singh – set theory

engineering colleges. Their first names
were Sarah (Ms.), Swati (Ms.), Jackie, Mohan and Priya (Ms.). The
surnames were Reddy, Gupta, Sanyal, Kumar and Chatterjee. Except for one
college which was rated as 3 star, all other colleges were rated either 4 star or 5 star.

one star less than the college where Sanyal studied. Only one college was rated
five star.

Read the following and choose the best alternative (Questions 13-15):
Decisions are often “risky in
the sense that their outcomes are not known with certainty. Presented with a choice
between a risky prospect that offers a 50 percent chance to win $200
(otherwise nothing) and an alternative of receiving $100 for sure, most
people prefer the sure gain over the gamble, although the two prospects have
the same expected value. (Expected value is the sum of possible outcomes weighted by their probability of occurrence.) Preference
for a sure outcome over risky prospect of equal expected
value is called risk averse; indeed, people tend to be risk averse when choosing between
prospects with positive outcomes. The tendency towards risk aversion can be explained by the notion
of diminishing sensitivity, first formalized by Daniel Bernoulli in 1738. Just
as the impact of a candle is greater when it is brought into a dark room than into a room that is well lit so,
suggested Bernoulli, the utility resulting from a small increase in wealth will
be inversely proportional to the amount of wealth already in one’s
possession. It has since been assumed
that people have a subjective utility function, and that preferences
should be described using expected
utility instead of expected value. According to expected utility, the worth of
a gamble offering
a 50 percent chance to win $200 (otherwise nothing) is 0.50 *
u($200), where u is the person’s concave utility function. (A function is
concave or convex if a line joining
two points on the curve lies
entirely below or above
the curves, respectively).
It follows from a concave
function that the subjective value attached to a gain of $100 is more than 50
percent of the value attached to a gain of $200, which entails preference for
the sure $100 gain and, hence, risk aversion.
Consider now a choice between losses. When asked to choose between a
prospect that offers a 50 percent chance
to lose $200 (otherwise nothing) and the alternative of losing $100 for sure,
most people prefer to take an
even chance at losing
$200 or nothing over
a sure $100
loss. This is because diminishing
sensitivity applies to negative as well as to positive outcomes: the impact of an initial $100 loss is greater than that of the next $100. This
results in a convex function for
losses and a preference for risky prospects over sure outcomes of equal
expected value, called risk seeking.
With the exception of prospects that involve
very small probabilities, risk aversion is generally
observed in choices involving
gains, whereas risk seeking tends
to hold in choices involving
losses.
Based on above passage, analyse the decision situations faced by
three persons: Babu, Babitha and Bablu.
13. Suppose instant and further utility of each unit of gain is same for
Babu. Babu has decided to play as many times as possible, before he dies. He
expected to live for another 50 years.
A game does not last more than ten
seconds. Babu is confused which theory to trust for making decision and seeks
help of a
renowned decision making
consultant: Roy Associates. What should be Roy Associate’s advice to
Babu?
A. Babu can decide on the basis of Expected Value hypothesis.
B. Babu should decide on the basis of Expected Utility hypothesis.
C. “Mr. Babu, I’m redundant”.
D. A and B
E. A, B and C
14. Continuing with previous question, suppose Babitha can only
play one more
game, which theory would help in
arriving at better decision?
A. Expected Value.
B. Expected Utility.
C. Both theories will give same results.
D. None of the two.
E. Data is insufficient to answer the question.
15. Bablu had four options with probability of 0.1, 0.25, 0.5 and 1. The
gains associated with each options are: $1000, $400, $200 and $100
respectively. Bablu chose the first
option. As per expected value hypothesis:
A. Bablu is risk taking.
B. Expected value function is concave.
C. Expected value function is convex.
D. It does not matter which option should Babu choose.
E. None of above.
