Master Caselet Data Interpretation. Learn to extract data from paragraphs into Tables and Venn Diagrams. Covers Arithmetic, Logical, and Flow-based Caselets.
<ul class='list-disc pl-6'>
<li><strong>Scenario:</strong> Data involves groups with overlaps (e.g., Read Newspaper A, B, C; Play Cricket, Football).</li>
<li><strong>The Formulas (3 Sets):</strong> <br>
Total = n(A) + n(B) + n(C) - n(AтИйB) - n(BтИйC) - n(CтИйA) + n(AтИйBтИйC) + None.
</li>
<li><strong>Strategy:</strong> Start from the innermost intersection (All 3) and work outwards.</li>
<li><strong>Regions:</strong> <br>
"Exactly 2" = (AтИйB only) + (BтИйC only) + (CтИйA only).
</li>
</ul>
Example:
<ul class='list-disc pl-6'>
<li><strong>Scenario:</strong> A paragraph describes a hierarchy. Total Employees -> Departments -> Male/Female -> Graduate/PG.</li>
<li><strong>Strategy:</strong> Draw a Tree Diagram or Table immediately. Do not read the whole text twice.</li>
<li><strong>Calculation Tip:</strong> Use a base number (like 100 or x) if total is missing, but usually Total is given.</li>
</ul>
Example:
<ul class='list-disc pl-6'>
<li><strong>Scenario:</strong> A story problem involving Profit/Loss, SI/CI, or Time/Distance for multiple people.</li>
<li><strong>Strategy:</strong> Treat it like multiple arithmetic word problems linked by common data.</li>
<li><strong>Example:</strong> Three friends invest money. A invests for 2 years, B for 3...</li>
