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