Let x and y denote [the exact areas could not be verified]. Which relation holds?
Elementary MathematicsMensuration
- Aπx=2y
- B2πx=y
- Cπx=4y
- Dπx=8y
Explanation
x and y denote areas whose definitions could not be recovered (options pi*x=2y, 2*pi*x=y, pi*x=4y, pi*x=8y). The stored key D agrees with the published coaching key (PW, CDS 2 2025 Set A). Note: key disputed - independent verification inconclusive.
