यदि \(A\setminus B={1,4}\), \(A\cap B={2,3}\) और \(B\setminus A={5,6,7}\), तो \(A\cup B\) क्या है?
If \(A\setminus B={1,4}\), \(A\cap B={2,3}\) and \(B\setminus A={5,6,7}\), what is \(A\cup B\)?
Explanation opens after your attempt
Correct Answer
A. ({1,2,3,4,5,6,7})
Concept
The union is made from the three disjoint parts \(A\setminus B\), \(A\cap B\), and \(B\setminus A\). Combining all gives ({1,2,3,4,5,6,7}).
Why this answer is correct
The correct answer is A. ({1,2,3,4,5,6,7}). The union is made from the three disjoint parts \(A\setminus B\), \(A\cap B\), and \(B\setminus A\). Combining all gives ({1,2,3,4,5,6,7}).
Exam Tip
संघ तीन असंयुक्त भागों \(A\setminus B\), \(A\cap B\), और \(B\setminus A\) से बनता है। सभी तत्व मिलाकर ({1,2,3,4,5,6,7}) मिलते हैं।
