यदि \(A\setminus B=B\setminus A\), तो कौन सा निष्कर्ष सही है?
If \(A\setminus B=B\setminus A\), which conclusion is correct?
Explanation opens after your attempt
Correct Answer
A. (A=B)
Concept
The sets \(A\setminus B\) and \(B\setminus A\) are always disjoint, so if they are equal, both are empty. Hence (A=B).
Why this answer is correct
The correct answer is A. (A=B). The sets \(A\setminus B\) and \(B\setminus A\) are always disjoint, so if they are equal, both are empty. Hence (A=B).
Exam Tip
\(A\setminus B\) और \(B\setminus A\) सदैव असंयुक्त होते हैं, इसलिए उनके बराबर होने पर दोनों खाली होंगे। अतः (A=B) है।
