यदि \(A\cap B={3,5}\), \(A\setminus B={1,7}\) और \(B\setminus A={2,9}\) है, तो (A) क्या होगा?
If \(A\cap B={3,5}\), \(A\setminus B={1,7}\), and \(B\setminus A={2,9}\), what is (A)?
Explanation opens after your attempt
Correct Answer
A. ( {1,3,5,7} )
Concept
Set (A) contains both parts \(A\setminus B\) and \(A\cap B\). Hence \(A=\{1,3,5,7\}\).
Why this answer is correct
The correct answer is A. ( {1,3,5,7} ). Set (A) contains both parts \(A\setminus B\) and \(A\cap B\). Hence \(A=\{1,3,5,7\}\).
Exam Tip
समुच्चय (A) में \(A\setminus B\) और \(A\cap B\) दोनों भाग आते हैं। इसलिए \(A=\{1,3,5,7\}\) है।
