Caselet
What
is a Data Caselet?
A
Caselet is a set of information that is given in paragraph form. In a
Caselet, no tables or graphs are given. You have to read the
information and draw a table or organize the given data to solve the
questions. Practice a lot of caselets based questions to master such
questions.

Tips for Data Caselets
-
It helps to convert a caselet into table or any other pictorial form.
-
Keep jotting down the important points in a caselet while reading it for the first time. Use notations to represent names of things, places, people, etc.
-
Be careful of the data given and the units as well. You need to be aware of basic conversions and units. For example, what do the terms million/billion/trillion stand for.
-
Make sure you use the options and approximations to avoid lengthy calculations.
-
Cover arithmetic related topics (interest, percentage, ratio & proportion) as questions in caselets are often based on concepts from this area.
Use
these five simple tips to ace data caselets:
Let's
solve a solve caselet now and see how to approach these questions.
Sample
Data CaseletGiven
below is a Caselet to help you understand and learn how it is solved:
Directions:
Refer to the information given below and answer the questions that
follow.
There
are 4 players in the cigar market of the Dominician Republic:
Amergio, Byford, Christie's and Ducatti. The sales in 1995 are of $
100,000 (100,000 boxes of cigars) - the volumes shared by Amergio,
Byford, Christie's and Ducatti are in the ratio of 1: 2: 3: 4 and the
sales is in the ratio of 4:3:2:1 respectively. The sales in 1996 show
a sharp drop - both in terms of volume and in dollars. In volume
terms, the demand fell by 60% and in dollar terms the figure was 50%.
The shares of Amergio, Byford, Christie and Ducatti in volume terms
was 2:2:3:3 and that of the ratio of prices charged was 9:6:3:1. The
market picked up dramatically in 1997 - the volumes were the sum
total sold in 1995 and 1996 and the sales rose by 390% over that of
1996. For 1997, sales by Christie have amounted to $84,000, which was
20% more than that made by Amergio and thrice the sales of Ducatti.
The volumes share in that year was in the ratio of 1:3:4:2.
Example
1: What
was the ratio of the prices charged by Amergio, Byford, Christie's
and Ducatti in 1997?
Solution: Summarising
the whole information, we can deduce the following:
1.
Value
For
year 1995:
Sales
(in value) 100,000 $
Ratio
of value for:
Amergio:
Byford: Christie: Ducatti= 4 : 3 : 2 : 1 = 40,000 : 30,000 : 20,000 :
10,000
For
year 1996:
Sales
(in value) = 50,000$
For
year 1997:
Total
Sales (Value) = 50 × 4.9 = 245,000
Example
2: In
which year was Sohan born?
A.
Sohan at present is 25 years younger to his mother.
B.
Sohan's Sister, who was born in 1964, is 35 years younger to his
mother.
Solution: From
both I and II, we find that Sohan is (35 - 25) = 10 years older than
his sister, who was born in 1964. So, Sohan was born in 1954.
Since,
we are getting unique answer from both statements when combined, so
the answer
is 3rdoption.
