यदि \(A\setminus B=\varnothing\) और \(B\setminus A=\varnothing\) है, तो कौन-सा निष्कर्ष सही है?
If \(A\setminus B=\varnothing\) and \(B\setminus A=\varnothing\), which conclusion is correct?
Explanation opens after your attempt
Correct Answer
A. (A=B)
Concept
Both differences being empty means each set is contained in the other, so (A=B). To prove equality, check both containments.
Why this answer is correct
The correct answer is A. (A=B). Both differences being empty means each set is contained in the other, so (A=B). To prove equality, check both containments.
Exam Tip
दोनों अंतर रिक्त होने का अर्थ है कि दोनों समुच्चय एक-दूसरे में समाहित हैं, इसलिए (A=B)। समानता सिद्ध करने में दोनों दिशाएं जांचें।
