The worked question on this page is original educational practice. It is not represented as a question from an official previous-year examination paper.

Review the question
Build original charts from a numerical table so every angle can be checked. Ask both largest-share and largest-amount questions to show when the rankings do and do not coincide.
02 / UNDERSTANDING
The concept in context
Sector size shows a relative share, not an absolute amount independent of the total. A smaller slice in a much larger pie can represent more units than a larger slice in a smaller pie. Read each chart’s base separately and verify whether categories exhaust the whole before combining information across charts.

A worked learning case
Original educational case. In an original expenditure chart with a total of ₹72,000, a 90-degree sector represents one quarter, or ₹18,000. A second chart totals ₹1,20,000 and has a 72-degree sector worth ₹24,000. The second sector has a smaller angle but a larger amount because its overall base is greater.
ORIGINAL EDUCATIONAL PRACTICE
Try it before you check.
Original practice: A 60-degree sector belongs to a pie representing 900 items. How many items does it represent?
Show the answer and reasoning
150 items.
The sector is 60/360, or one sixth, of the complete circle. One sixth of 900 is 150. Using 60 as a percentage would incorrectly treat an angle measurement as a percent share. The calculation requires both the sector angle and the total represented by the full pie.
Two traps to watch for.
- Treating degrees as if they were percentages.
- Comparing sector amounts across charts without checking totals.
YOUR TOPIC-SPECIFIC LEARNING MAP
Learn from the attempt
Convert each sector into a fraction.
Write the full-pie total beside the chart.
Check whether all category amounts sum correctly.
Explain the idea, apply it to a new situation, then check what changed in your reasoning.
