Find the odd everyday object (torus with hole vs solid disc): Select the option that is not a ring-like, hollow circular object.

Difficulty: Easy

Correct Answer: Plate

Explanation:


Introduction / Context:
Shape-based classification is a robust method in reasoning questions. Here, three options are circular with a central hole facilitating wearing, mounting, or rotation, while one is a solid disc without a through-hole. The presence or absence of a hole is an objective geometric discriminator.



Given Data / Assumptions:

  • Ring: circular band with a central hole.
  • Tyre: torus-like circular object with a central hole for the wheel rim.
  • Bangle: circular band worn around the wrist, with a central opening.
  • Plate: generally a flat, solid disc without a central hole.


Concept / Approach:
Group by topology: torus-like objects with a central aperture versus a solid disc. The functional design of ring, tyre, and bangle depends on the hole; a plate does not share that property.



Step-by-Step Solution:

1) Identify items with central holes: Ring, Tyre, Bangle.2) Identify the item without a hole: Plate.3) Plate is the odd one out.


Verification / Alternative check:
Consider usage: the hole enables wearing or mounting; plates serve as surfaces, not mounts.



Why Other Options Are Wrong:
They all belong to the hollow circular class with an essential central opening.



Common Pitfalls:
Do not be misled by materials or size; the decisive feature is the presence of a through-hole.



Final Answer:
Plate
