किस स्थिति में \(A\setminus B=A\cap B\) सत्य हो सकता है?
In which situation can \(A\setminus B=A\cap B\) be true?
Explanation opens after your attempt
Correct Answer
A. \(A=\varnothing\)
Concept
The sets \(A\setminus B\) and \(A\cap B\) are disjoint, so if they are equal, both must be empty. This gives \(A=\varnothing\).
Why this answer is correct
The correct answer is A. \(A=\varnothing\). The sets \(A\setminus B\) and \(A\cap B\) are disjoint, so if they are equal, both must be empty. This gives \(A=\varnothing\).
Exam Tip
\(A\setminus B\) और \(A\cap B\) असंयुक्त होते हैं, इसलिए बराबर होने पर दोनों खाली होंगे। इससे \(A=\varnothing\) मिलता है।
