Data Interpretation (DI) is one of the most important sections in bank exams. It tests calculation speed, data analysis, and accuracy.
1. Types of DI
- Table DI
- Bar Graph
- Pie Chart
- Line Graph
- Caselet DI
2. Table Method (Most Important)
Convert given data into a simple table format before solving.
Helps reduce confusion and saves time
3. Approximation Trick
Use rounding to simplify calculations.
Example:
498 ≈ 500
102 ≈ 100
498 × 102 ≈ 500 × 100 = 50000
4. Percentage Based DI
Most DI questions involve percentage.
