यदि \(A=\{1,2,3,4,5\}\) और \(B=\{2,4,6\}\), तो (\(A\cup B\)-\(A\cap B\)) क्या है?
If \(A=\{1,2,3,4,5\}\) and \(B=\{2,4,6\}\), what is (\(A\cup B\)-\(A\cap B\))?
Explanation opens after your attempt
Correct Answer
B. ( {1,3,5,6} )
Step 1
Concept
\(A\cup B={1,2,3,4,5,6}\) and \(A\cap B={2,4}\). Taking the difference gives ({1,3,5,6}).
Step 2
Why this answer is correct
The correct answer is B. ( {1,3,5,6} ). \(A\cup B={1,2,3,4,5,6}\) and \(A\cap B={2,4}\). Taking the difference gives ({1,3,5,6}).
Step 3
Exam Tip
\(A\cup B={1,2,3,4,5,6}\) और \(A\cap B={2,4}\) है। अंतर लेने पर ({1,3,5,6}) मिलता है।

यदि \(A=\{1,3,5,7,9\}\), \(B=\{2,3,5,8\}\) और \(C=\{3,4,5,6\}\) है, तो (A-\(B\cap C\)) क्या है?
If \(A=\{1,3,5,7,9\}\), \(B=\{2,3,5,8\}\), and \(C=\{3,4,5,6\}\), what is (A-\(B\cap C\))?

Correct Answer
A. ( {1,7,9} )
Step 1
Concept
\(B\cap C={3,5}\). Removing these from (A) gives ({1,7,9}).
Step 2
Why this answer is correct
The correct answer is A. ( {1,7,9} ). \(B\cap C={3,5}\). Removing these from (A) gives ({1,7,9}).
Step 3
Exam Tip
\(B\cap C={3,5}\) है। इन्हें (A) से हटाने पर ({1,7,9}) मिलता है।

Correct Answer
A. ( {1,5,9} )
Step 1
Concept
The union is ( {1,3,5,7,9} ) and the intersection is ( {3,7} ). Removing the intersection leaves ( {1,5,9} ).
Step 2
Why this answer is correct
The correct answer is A. ( {1,5,9} ). The union is ( {1,3,5,7,9} ) and the intersection is ( {3,7} ). Removing the intersection leaves ( {1,5,9} ).
Step 3
Exam Tip
संघ ( {1,3,5,7,9} ) और प्रतिच्छेद ( {3,7} ) है। प्रतिच्छेद हटाने पर ( {1,5,9} ) बचता है।
