Welcome to KAMAL ACADEMY! In this video, Sir Ibrahim Kamal breaks down a highly important and frequently asked Mathematics MCQ for Cadet College entry tests.

❓ The Question: If A is a subset of B (A ⊆ B), then what is A ∪ B (A Union B) and A ∩ B (A Intersection B)?

Instead of wasting precious exam time plugging in random numbers, this lecture teaches you the conceptual logic and short tricks behind Subsets and Super-sets. You will learn how to find the Union and Intersection instantly just by looking at the condition!

💡 What you will learn in this video:
- The true conceptual meaning of a Subset (with clear examples).
- Why the Union (A ∪ B) of a subset always results in the Super-set.
- Why the Intersection (A ∩ B) of a subset always results in the Subset itself.
- Quick shortcuts to solve similar Set Theory MCQs in seconds.

This video is essential for students preparing for Cadet College admission tests, school exams, and competitive entry tests.
