Pie Chart Test — Frequently Asked Questions

What is the fastest way to handle a pie-chart set?+

If the total is given, convert every sector into an absolute value in one pass before reading the questions. Most questions then become simple addition or subtraction.

How do I find a missing sector?+

Subtract the sum of the known sectors from 100% (or from 360° if the chart is in degrees). It is always faster than any other route.
