यदि \(A=\{2,3,4,5\}\) और \(B=\{4,5,6,7\}\) हैं, तो कौन सा कथन असत्य है?
If \(A=\{2,3,4,5\}\) and \(B=\{4,5,6,7\}\), which statement is false?
Explanation opens after your attempt
Correct Answer
D. \(B\setminus A={2,3}\)
Concept
\(B\setminus A\) contains elements of (B) that are not in (A), namely ({6,7}). In difference, changing order changes the answer.
Why this answer is correct
The correct answer is D. \(B\setminus A={2,3}\). \(B\setminus A\) contains elements of (B) that are not in (A), namely ({6,7}). In difference, changing order changes the answer.
Exam Tip
\(B\setminus A\) में (B) के वे अवयव होंगे जो (A) में नहीं हैं, यानी ({6,7})। अंतर में क्रम बदलने से उत्तर बदलता है।
