Data Caselets based questions are asked in Data Interpretation sections of almost all competitive exams like CAT, XAT, NMAT, SNAP, etc. Considering the importance of this question type, it is important you understand the fundamentals of Data Caselets.
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.

Given 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 3rd option.
