यदि \(A\subseteq B\), तो (A\cup\(B\setminus A\)) किसके बराबर है?
If \(A\subseteq B\), then (A\cup\(B\setminus A\)) is equal to which set?
Explanation opens after your attempt
Correct Answer
A. (B)
Concept
When \(A\subseteq B\), the elements of (B) split into (A) and \(B\setminus A\). Therefore their union is (B).
Why this answer is correct
The correct answer is A. (B). When \(A\subseteq B\), the elements of (B) split into (A) and \(B\setminus A\). Therefore their union is (B).
Exam Tip
जब \(A\subseteq B\) हो, तो (B) के तत्व (A) और \(B\setminus A\) में बँट जाते हैं। इसलिए उनका संघ (B) है।
