| School | Appeared (2020) | Passed (2020) | Appeared (2021) | Passed (2021) |
|---|---|---|---|---|
| A | 500 | 400 | 600 | 480 |
| B | 400 | 300 | 500 | 375 |

| E | 200 | 150 | 300 | 225 |
Note: Pass Percentage = (Passed / Appeared) × 100
Tables in Data Interpretation are structured arrangements of data in rows and columns. They present numerical information about various parameters like sales, production, population, etc. In SSC CGL, table-based DI questions are guaranteed to appear in every paper, usually 3-5 questions per table. Key Rules for Table Analysis:
1. Always read the title and column headers first 2. Identify what each row and column represents
3. Check for units mentioned (lakhs, crores, percentage, etc.) 4. Look for missing data or symbols like '-' or '*'
5. Understand the time period covered Common Question Types:
• Finding totals, averages, and percentages • Comparison between years/categories
• Growth rate calculations • Ratio and proportion problems
• Maximum/minimum value identification
Shortcut 1 - Quick Percentage Calculation:
For 25%: Divide by 4
For 20%: Divide by 5
For 12.5%: Divide by 8
Shortcut 2 - Average Estimation:
When finding average of 5-6 numbers, pick a round number close to all values. Calculate differences and adjust.
Shortcut 3 - Ratio Comparison:
Find total sales = 120 + 150 + 180 + 90 + 160 = 700 lakhs
Company C's sales = 180 lakhs
Percentage = (180/700) × 100 = 18/7 × 10 = 25.71% Answer: Approximately 25.7% Worked Example 2: Production table shows Year 2019: 240 units, Year 2020: 180 units Question: Find percentage decrease from 2019 to 2020.
Decrease = 240 - 180 = 60 units
Percentage decrease = (60/240) × 100
= (1/4) × 100 = 25% Answer: 25% decrease
• Tables usually have 4-6 rows and 4-7 columns • Data often represents years (2015-2020) or categories • Questions test calculation speed and accuracy • Answer choices are often close, requiring precise calculation • Time allocation: Maximum 2-3 minutes per question Most Common Trap - The #1 Mistake: Students often miss the UNITS mentioned in table headers. A table showing '245' with header 'Sales (in crores)' means 245 crores, not 245 rupees. This unit confusion leads to wrong final answers even with correct calculations. Always circle the units before starting calculations
• Use approximation for complex calculations when answer choices are far apart • Eliminate obviously wrong options first • For percentage questions, convert to fractions when possible • Practice mental math for common calculations (squares, percentages, ratios) Success Strategy: Table DI is purely calculation-based. Focus on accuracy over speed initially. Build calculation speed through regular practice. Master basic arithmetic operations and percentage calculations.
These questions are scoring if approached systematically.
