CORE CONCEPT — WHAT IS A PIE CHART? A pie chart is a circle divided into slices. Each slice shows the share of one category out of the total. The full circle = 360 degrees = 100%. In SSC CGL, pie charts come with data in degrees OR percentages. Your job is to find values, differences, ratios, and percentages from the chart.
The total of all slices = 360 degrees (always).
The total of all percentages = 100% (always).
Each degree = 1/360 of the total value.
Each percent = 1/100 of the total value.
If a slice is given in degrees, convert to percentage: Percentage = (Degree / 360) x 100.
If a slice is given in percentage, convert to degrees: Degree = (Percentage / 100) x 360.
- Find the value of one category (given total). - Find the difference between two categories. - Find the ratio of two categories. - Find what percentage one category is of another category. - Compare two pie charts (e.g., production vs export). - Find the percentage increase or decrease from one chart to another. SHORTCUTS AND TRICKS Trick 1 — Direct Ratio Shortcut: Never convert degrees to values just to find a ratio. The ratio of two categories equals the ratio of their degrees or percentages directly
If category A = 72 degrees and category B = 108 degrees, ratio = 72:108 = 2:3. No need for total
If a question asks what percentage is Category A of Category B: Answer = (Percentage of A / Percentage of B) x 100 Example: A = 25%, B = 40%. Answer = (25/40) x 100 = 62.5% Trick 3 — Two Pie Chart Comparison: When two pie charts show data for two years with different totals, DO NOT compare percentages directly. Always calculate actual values first using (Percentage / 100) x Total.
Combined percentage = 30 + 25 = 55%
Amount = (55 / 100) x 50,000 = Rs 27,500 Answer: Rs 27,500 Question: What is the ratio of Education to Others?
Education = 20%, Others = 10%
Ratio = 20:10 = 2:1 (Use Trick 1 — no calculation needed) Answer: 2:1 WORKED EXAMPLE 2 A pie chart shows production of a factory in degrees. Total production = 7200 units. Product A = 90 degrees, Product B = 120 degrees, Product C = 150 degrees. Question: How many units of Product B were produced?
Value = (Degree / 360) x Total
Value = (120 / 360) x 7200 = (1/3) x 7200 = 2400 units Answer: 2400 units Question: What percentage of total production is Product A?
Percentage = (90 / 360) x 100 = 25% Answer: 25%
— THE NUMBER 1 TRAP Students compare percentages across two different pie charts when the totals are different. This is WRONG. Example: In Year 1, Exports = 40% of total production 10,000 = 4,000 units. In Year 2, Exports = 35% of total production 15,000 = 5,250 units.
Even though the percentage went DOWN, the actual value went UP. Always calculate actual values when totals differ. This trap appears in almost every SSC CGL paper.
