🔹 Data Interpretation (DI) Tricks
Data Interpretation questions are crucial in bank exams, especially in mains. Speed calculation and smart analysis are key to solving DI sets efficiently.
✅ Trick 1: Approximation in DI
Concept: Round values to simplify calculations.
Example: 498 ≈ 500, 202 ≈ 200
- 500 × 200 = 100000
- Adjust slightly for accuracy
✅ Trick 2: Percentage to Fraction
Example: 25% = 1/4, 20% = 1/5
- Use fraction instead of percentage for faster solving
✅ Trick 3: Ratio Comparison
Compare values using ratios instead of calculating exact numbers.
✅ Trick 4: Data Simplification
Simplify large numbers by dividing or rounding before calculation.
🔹 Sample DI Set (Table-Based)
Sales Data (in units):
| Year | Product A | Product B | Product C |
|---|---|---|---|
| 2021 | 480 | 520 | 610 |
