यदि (A\setminus\(B\cap C\)) को सरल करना हो, तो सही विकल्प कौन-सा है?
If (A\setminus\(B\cap C\)) is simplified, which option is correct?
Explanation opens after your attempt
A. (\(A\setminus B\)\cup\(A\setminus C\))
Concept
An element not in \(B\cap C\) is missing from at least one of (B) or (C). Hence union appears, not intersection.
Why this answer is correct
The correct answer is A. (\(A\setminus B\)\cup\(A\setminus C\)). An element not in \(B\cap C\) is missing from at least one of (B) or (C). Hence union appears, not intersection.
Exam Tip
जो तत्व \(B\cap C\) में नहीं है, वह कम-से-कम (B) या (C) में नहीं होगा। इसलिए संघ आता है, प्रतिच्छेद नहीं।
