DILRCaselets
Caselets: Text-Based DI
What are Caselets?
Paragraph-based data presentation requiring:
- Reading comprehension
- Data extraction
- Logical reasoning
- Calculations
Reading Strategy
First Pass (60 seconds)
- Identify variables
- Note relationships
- Spot constraints
- Don't calculate yet
Second Pass (Per Question)
- Extract relevant data
- Organize in table/diagram
- Calculate step by step
Common Caselet Types
Business Scenarios
- Sales, Profit, Revenue
- Multiple products/regions/time periods
- Percentage changes, ratios
Tournament/Games
- Matches played, won, lost
- Points system
- Rankings
Venn Diagram Based
- Set theory problems
- Overlapping categories
- Use formula: n(A∪B) = n(A) + n(B) - n(A∩B)
Process/Flow
- Sequential operations
- Input-output relationships
- Efficiency calculations
Solution Techniques
Organize Data
- Create table from text
- List knowns and unknowns
- Identify what's asked
Use Variables
- If values not given, assume variables
- Set up equations
- Solve systematically
Verify Consistency
- Check if all conditions satisfied
- Look for contradictions
- Validate answer against all clues
Common Calculations
Percentage
- Increase/Decrease
- Percentage points vs Percentage change
- Base value identification
Ratios
- Part-to-part vs Part-to-whole
- Combining ratios
- Ratio to actual values
Averages
- Simple average
- Weighted average
- Moving average
CAT Strategy
- Read all questions before solving
- Identify interdependent questions
- Solve easier questions first
- Use answer options to verify
- Time: 10-12 minutes for 4-question set
Practice Tip
- Convert text to structured format (table/diagram)
- Practice extracting key information quickly
- Build speed in percentage calculations
