Data Interpretation: Caselet DI

Concept Explanation

Caselet DI presents data as a short paragraph instead of a chart. You must extract numbers and relationships from text.

How to Read a Caselet

• Underline all numeric facts and what they refer to.
• Build a mini-table mentally before calculating.
• Watch for “respectively,” “more than,” and “of the remaining.”

Key Formulas

• Translate “A is 20% more than B” to A = 1.2B.
• For ratios, assign variables (e.g., 3x and 5x).
• Sum parts when the caselet gives sequential splits.

Example

“Shop sold 120 units in Jan and 150 in Feb.” Total = 270; Feb is 25% more than Jan.

Common Trap

Percentage “of the remaining” uses a new base after the first deduction.
