Pie Chart DI

Master Pie Charts. Learn Degree to Percentage conversion, Double Pie logic, and Missing Data analysis.

Model 1: Degree to Percentage Conversion

<ul class='list-disc pl-6'> <li><strong>The Core Rule:</strong> A full circle is 360┬░ and also 100%.</li> <li><strong>Conversion Logic:</strong> <br> 100% = 360┬░ <br> 10% = 36┬░ <br> 1% = 3.6┬░ </li> <li><strong>Formula:</strong> <br> Value in % = (Value in Degrees / 360) ├Ч 100 <br> Value in Degrees = (Value in % / 100) ├Ч 360 </li> </ul>

Example:

Q: Convert 72┬░ into percentage.
Solution: (72 / 360) ├Ч 100 = (1/5) ├Ч 100 = 20%.

Model 2: The Double Pie Chart

<ul class='list-disc pl-6'> <li><strong>Scenario:</strong> Two pie charts are given. One for Total Population, another for Female Population.</li> <li><strong>The Logic:</strong> You need to find Male Population.</li> <li><strong>Strategy:</strong> <br> Males = Total(Sector) - Females(Sector). <br> Calculate real values first, then subtract. Do not subtract percentages directly unless Base values are same (rare). </li> </ul>

Example:

Q: Total=1000 (A=20%), Females=400 (A=30%). Find Males in A.
Solution: Total A = 20% of 1000 = 200. Female A = 30% of 400 = 120. Male A = 200 - 120 = 80.

Model 3: The 'Missing Slice' Trap

<ul class='list-disc pl-6'> <li><strong>Scenario:</strong> One sector in the pie chart is blank or labeled 'Others'.</li> <li><strong>The Logic:</strong> The sum of all sectors must be 100% (or 360┬░).</li> <li><strong>Hack:</strong> <br> Missing % = 100% - (Sum of known %). <br> Missing Degee = 360┬░ - (Sum of known ┬░). </li> </ul>

Example:

Q: Pie: A=40%, B=35%, C=?. Find C.
Solution: C = 100% - (40+35)% = 100% - 75% = 25%.
