Caselets (paragraph DI)— Rules & Concept

Core ConceptRead this first — the foundation of the topic

Caselets in Data Interpretation are paragraph-based questions where data is presented in story format instead of charts or tables. These questions test your ability to extract numerical information from text and perform calculations. In SSC CGL, caselets typically appear as 3-5 questions based on one paragraph containing business scenarios, financial data, or statistical information. Key characteristics of caselets include mixed data presentation, multiple calculation steps, and real-world contexts like company profits, population studies, or survey results. The data is embedded within sentences, requiring careful reading to identify relevant numbers and relationships.

Common caselet patterns in SSC CGL include percentage calculations (profit/loss, growth rates), ratio and proportion problems, average and percentage combination, and simple interest/compound interest scenarios. Questions often involve finding missing values, comparing different entities, or calculating derived metrics. Formulas frequently used:

Percentage increase/decrease = (New Value - Old Value)/Old Value × 100 Average = Sum of all values/Number of values

Ratio calculation = Part/Whole × 100 Profit percentage = (Selling Price - Cost Price)/Cost Price × 100

ShortcutsUse these to save 30–60 seconds per question

Create a data extraction table while reading. Write down all numerical values with their labels in tabular format. This prevents re-reading and saves 30-40 seconds per question.

Worked ExampleSolve this step-by-step before moving on
1
Step 1

Extract data 2022 revenue = 50 lakhs 2023 revenue = 50 + 20% of 50 = 50 + 10 = 60 lakhs 2023 expenses = 60% of 60 = 36 lakhs 2023 profit = 16 lakhs

2
Step 2

Verify (Revenue - Expenses = Profit) 60 - 36 = 24 lakhs (but profit given as 16 lakhs, so expenses = 60 - 16 = 44 lakhs)

3
Step 3

Calculate expense percentage of 2022 revenue Expense percentage = (44/50) × 100 = 88% Another useful trick: Use approximation for quick elimination. If exact calculation seems time-consuming, round numbers to nearest 5 or 10 for faster computation, then match with closest option.

Exam TrapsCommon mistakes students make — avoid these

include misidentifying which year/entity the question refers to, mixing up base values for percentage calculations, and not verifying if calculated values make logical sense. Always cross-check your final answer against the given constraints in the paragraph.

Key Points to Remember

  • Caselets present data in paragraph format rather than charts or tables
  • Extract all numerical data into a separate table while reading to avoid re-reading
  • Questions typically involve 2-3 calculation steps combining different concepts
  • Common themes include profit-loss, growth rates, surveys, and financial scenarios
  • Always verify which time period or entity the question is asking about
  • Use approximation technique to eliminate wrong options quickly
  • Cross-check final answers against logical constraints given in paragraph
  • Percentage base identification is crucial - carefully note what the percentage is calculated on

Exam-Specific Tips

  • SSC CGL typically includes 2-3 caselet sets with 3-5 questions each in Tier-1
  • Each caselet question carries 2 marks with 0.5 negative marking
  • Average solving time per caselet question should be 90-120 seconds
  • Caselets often combine 2-3 topics like percentages with ratios or averages with profit-loss
  • Data extraction from paragraph format appears in 15-20% of total DI questions
  • Business scenario caselets are 60% more frequent than survey-based caselets
  • Mixed calculation caselets have appeared in last 8 consecutive SSC CGL papers

60-Second Revision — Caselets (paragraph DI)

  • Remember: Create data table immediately after reading the caselet paragraph
  • Formula: Percentage change = (New-Old)/Old × 100, check the base value carefully
  • Trick: Use approximation for elimination, exact calculation only for final answer
  • Trap: Questions often mix time periods or entities - underline key terms
  • Pattern: Most caselets involve 2-step calculations combining different concepts
  • Strategy: Verify final answer makes logical sense within given constraints
  • Time management: Spend maximum 6-7 minutes on complete caselet set
