यदि \(A\subseteq B\) है, तो (\(A\cup B\)\setminus\(A\cap B\)) किसके बराबर है?
If \(A\subseteq B\), then (\(A\cup B\)\setminus\(A\cap B\)) is equal to which set?
Explanation opens after your attempt
Correct Answer
A. \(B\setminus A\)
Concept
When \(A\subseteq B\), \(A\cup B=B\) and \(A\cap B=A\), hence the answer is \(B\setminus A\). Apply the subset condition first.
Why this answer is correct
The correct answer is A. \(B\setminus A\). When \(A\subseteq B\), \(A\cup B=B\) and \(A\cap B=A\), hence the answer is \(B\setminus A\). Apply the subset condition first.
Exam Tip
जब \(A\subseteq B\), तब \(A\cup B=B\) और \(A\cap B=A\), इसलिए उत्तर \(B\setminus A\) है। उपसमुच्चय की शर्त पहले लगाएं।
