Types Of Data Interpretation
Here’s a breakdown of common DI formats with smart solving tips:
- Table-Based DI: Presents data in rows and columns based on figures like sales, population, production, scores, etc. Requires careful reading and quick math using percentages, ratios, or averages.
- Bar Graphs & Column Charts: Compare categories visually. Solve by bar heights or lengths, then apply subtraction or ratios for comparisons.
- Line Graphs: Show trends over time or categories. Focus on patterns and incremental changes rather than raw numbers to derive faster insights.
- Pie Charts (Single & Double): Great for visual distribution of data. Converting sectors to percentages and then deriving numbers is key. Double pie charts appear often and require correlating two different distributions.
- Caselet DI: Text-based mini-passages containing embedded numerical data. Organise info systematically (e.g., jotting down in a mini-table) for clarity.
- Mixed DI Sets: Combine multiple DI styles, making them more challenging. Often seen in mains to test layered computation and logical reasoning.

Quick-Solving Strategies for Each DI Type
Here we are providing a quick solving strategy for DI questions. Candidates must follow this strategy to boost their question-solving speed.
- Memorise Key Formulas
Before starting to solve questions, you can memorise some Percentages, averages, ratios, time-work, time-speed-distance, profit & loss, and simple interest with instant recall. - Use Approximation & Simplification
Use round figures and estimation to eliminate impossible options quickly. - Convert to Ratios or Percentages
Especially useful with pie charts and comparison questions. - Practice Mental Math
DI demands speed: work on fast multiplier/divider shortcuts and simplifying complex operations. - Read Caselets Intelligently
Skim for numbers first, then decipher relationships and frame structured notes. - Avoid Clutter
Do only necessary computations, ignore irrelevant info. - Strategise Time Allocation
In pre-mains, spend no more than 2 minutes per DI set in prelims; allocate more strategically in mains.
