Caselets

Caselets are data interpretation sets where information is presented in a paragraph or story-like format instead of tables, charts, or graphs. They require you to read carefully, extract numerical data, and then organize it into a usable structure (like a table or diagram) before solving the questions.

Key Features of Caselets

  • Narrative Form: Data is embedded in sentences, often spread across multiple lines.
  • No Visuals Given: Unlike graphs/charts, you must create your own structure.
  • Multiple Variables: Typically involve categories like people, companies, sales, profits, percentages, or time.
  • Reasoning + Calculation: Requires both logical deduction and numerical operations.

How to Approach Caselet Questions

  1. Read the passage carefully: Identify quantities, comparisons, and conditions.
  2. Note key numbers/relations: Write them down in simplified form.
  3. Organize into a table/diagram: Convert the paragraph into a structured format.
  4. Solve step by step: Use percentages, ratios, or logical constraints to fill missing values.
  5. Cross-check: Ensure all conditions in the caselet are satisfied.

Conceptual Tips and Common Mistakes

  • Don’t skip structuring: Without a table, it’s easy to miss hidden constraints.
  • Highlight keywords: Words like more than, less than, twice, ratio are critical.
  • Beware of incomplete data: Some caselets allow only partial deductions.
  • Time management: Caselets can be lengthy; focus on building the base table first.

Examples

Example 1 — Sales Distribution

Passage: A company sells products A, B, and C. Together they sold 1,000 units. A sold 400, B sold 350.
Question: How many units did C sell?
Answer: 1,000 – (400 + 350) = 250.

Example 2 — Percentage Caselet

Passage: Out of 500 students, 60% are boys. Among boys, 40% play football.
Question: How many boys play football?
Answer: 500 × 60% × 40% = 120.

Example 3 — Ratio Caselet

Passage: In a company, the ratio of engineers to managers is 5:2. If there are 70 employees in total, find the number of engineers.
Answer: Engineers = (5/7) × 70 = 50.

Example 4 — Multi-Condition Caselet

Passage: Three friends (A, B, C) share ₹6,000. A gets twice as much as B, and C gets ₹1,000 more than B.
Question: How much does A get?
Solution: Let B = x → A = 2x, C = x + 1,000.
Equation: 2x + x + (x + 1,000) = 6,000 → 4x + 1,000 = 6,000 → x = 1,250.
So, A = 2x = 2,500.
