Data Sufficiency Questions and Answers

Q: Of what is an investment decision an example?

Correct answer: Non-programmed decisionA programmed decision is one that recurs in a familiar form and can be settled by an established rule or procedure - reordering stock at a set level, for instance. An investment decision is the opposite: it is infrequent, involves large sums committed for years, faces conditions that have not arisen before, and requires judgement rather than a rule. Such decisions are taken at senior level for exactly that reason.

3. Q is not taller than T and R

A.Only 1 and 2

Answer: A

From 1, we have: P > D, P > N, T > P i.e. T > P > D > N or T > P > N > D ...(i)

From 2, we have: R > Q, T > R i.e. T > R > Q ...(ii)

From 3, we have: T > Q, R > Q ...(iii)

Clearly, from (i) and (ii), we conclude that T is taller than each one of P, N, D, R and Q. So, T is the tallest.

How is 'DATE' written in the code language ?

Statements:

1. DEAR is written as $#@? in that code.

2. TREAT is written as %?#@% in that code.

3. TEAR is written as %#@? in that code,

A.Only 1 and 2
B.Only 2 and 3
C.All 1, 2 and 3
D.Only 1 and either 2 or 3

Answer: D

Observing 1, 2 and 3, we find that similar letters have similar code symbols at the corresponding places in the code. So, this is direct-coding.

Thus, to find the code for DATE, we need the code for D which can be obtained from 1 only (i.e. $.) and the codes for A, T and E which can be obtained either from 2 or 3 (@, # and % respectively).

An investment decision is the opposite: it is infrequent, involves large sums committed for years, faces conditions that have not arisen before, and requires judgement rather than a rule. Such decisions are taken at senior level for exactly that reason.
