How to Solve Caselet Data Interpretation Problems
Solve caselet data interpretation problems — converting prose into variables and tables, relative statements — with worked example and practice questions.
Expected Interview Answer
A caselet gives data as a written paragraph rather than a chart or table, so the first task is converting the prose into a small table or set of variables before attempting any calculation, since the paragraph format hides relationships that a table would show directly.
Read the caselet once fully without calculating, to understand the overall scenario and which entities and quantities are involved. On the second read, extract every numeric statement into a structured note — a mini-table or a list of variables and equations — since caselets often state a total and a few individual values, leaving one or more values to be derived. Watch for relative statements (“twice as many as,” “10 more than”) which must become algebraic relationships rather than direct numbers. Once the caselet is converted into structured data, it is solved exactly like a tabular DI problem — the difficulty is entirely in the extraction step, not the arithmetic.
- Converting prose to a table upfront prevents re-reading the paragraph for every sub-question
- Explicit variables for relative statements avoid misinterpreting comparative language
- Once structured, remaining arithmetic is simple ratio/percentage work
AI Mentor Explanation
A caselet describing a tournament in prose — “Team A scored 20 more runs than Team B, and Team C scored twice what Team A scored” — has to be converted into variables (B = x, A = x+20, C = 2(x+20)) before any total-runs question can be answered. Reading the paragraph once for the overall scenario, then a second time to extract every numeric relationship into a mini-table, mirrors how a scorer builds a scorecard from a ball-by-ball commentary. Once structured, computing each team’s share of the combined total is straightforward division, just like a normal table-based question.
Worked example
Extract variables
- B = x = 15
- A = x+10 = 25
Derive remaining
- C = 2A = 50
Total
- 15+25+50 = 90
Step-by-Step Explanation
Step 1
Read once for context
Understand the overall scenario and entities before calculating anything.
Step 2
Extract into variables
Convert every numeric or relative statement into a structured note or mini-table.
Step 3
Formalize relative language
"Twice as many,“ ”10 more than" become explicit algebraic relationships.
Step 4
Solve as a standard table
Once structured, apply normal ratio/percentage/total techniques.
What Interviewer Expects
- Systematic two-pass reading — context first, extraction second
- Correct conversion of comparative language into algebraic relationships
- A structured mini-table or variable list before any calculation
- Recognizing the caselet reduces to a standard DI problem once extracted
Common Mistakes
- Attempting to calculate while reading the paragraph the first time, causing missed relationships
- Misreading “twice as many as B“ as ”B is twice as many”
- Not writing down extracted variables, forcing repeated re-reading of the paragraph
- Treating a caselet as requiring different formulas than tabular DI, when the underlying math is identical
Best Answer (HR Friendly)
“For a caselet I always read the whole paragraph once just to understand the scenario, without trying to calculate anything yet. Then on a second pass I pull out every number and relationship into a small table or set of variables, being careful with phrases like twice as many or 10 more than, since those need to become equations rather than direct values. Once I have that structured note, the caselet becomes a normal data-interpretation problem and I solve it the same way I would a table.”
Follow-up Questions
- How do you handle a caselet where a value must be derived from two separate relative statements?
- What is the fastest way to structure a caselet with four or more entities?
- How would you verify your extracted variables are consistent with the whole paragraph?
- How does solving a caselet differ from solving the same data given as a table?
MCQ Practice
1. A caselet states "B has x items, A has 10 more than B, C has twice what A has." If B = 20, what is C?
A = 20+10 = 30; C = 2×30 = 60.
2. What should you do on the first read of a caselet paragraph?
The first read is for context; extraction and calculation come on the second pass.
3. A caselet says "C earned three times what B earned." This should be converted to?
"Three times what B earned" translates directly to C = 3B.
Flash Cards
First step with any caselet? — Read once fully for context, without calculating.
How to handle “twice as many as B”? — Convert to an explicit equation, e.g. A = 2B.
Why extract into a mini-table? — Avoids re-reading the paragraph for every sub-question.
How does a caselet differ mathematically from a table? — It does not — once extracted, it is solved with the same techniques.
