Premises — All the students in my class are intelligent. Kaushik is not intelligent.\nQuestion — What conclusion necessarily follows?

Introduction / Context:
This is the same syllogistic pattern earlier: “All S are I; Kaushik is not I.” Contraposition yields that Kaushik cannot be in S (the class). Avoid global generalizations beyond “my class.”

Given Data / Assumptions:

• S = students in my class; I = intelligent.
• All S → I; Kaushik is ¬I.

Concept / Approach:
If membership in S guarantees I, then ¬I entails ¬S for that individual. Hence Kaushik ∉ S.

Step-by-Step Solution:

Final Answer:
Kaushik is not a student of my class
