MAH-CET | Reasoning | 2025Which word does not belong to the group?
Choose the correct answer:
- A.
Dog
- B.
Cat
- C.
Bird
- D.
Car
(Correct Answer)
Car
Explanation
Biological Classification
Let the set of words be W={Dog, Cat, Bird, Car}.
We can define a subset A representing Living Organisms (Animals/Birds):
A={x∈W∣x is a biological living being}
A={Dog, Cat, Bird}
Logical Deduction
We compare the nature of each item:
-
Biological Entities:
-
Dog∈A (Mammal)
-
Cat∈A (Mammal)
-
Bird∈A (Aves)
-
-
Non-Biological Entity:
-
Car∈/A
-
Car∈Mechanical Objects (Vehicles)
-
Final Conclusion
The property that defines the group is "Life" or "Biological Being."
∀x∈{Dog, Cat, Bird},x is living⟹Car is the outlier.
