यदि \(A=\{1,2,3,4\}\) और \(B=\{3,4,5,6\}\) है, तो (A-B) और (B-A) का संघ क्या है?
If \(A=\{1,2,3,4\}\) and \(B=\{3,4,5,6\}\), what is the union of (A-B) and (B-A)?
Explanation opens after your attempt
Correct Answer
A. ( {1,2,5,6} )
Concept
(A-B={1,2}) and (B-A={5,6}), so the union is ({1,2,5,6}). It shows the parts outside the common part.
Why this answer is correct
The correct answer is A. ( {1,2,5,6} ). (A-B={1,2}) and (B-A={5,6}), so the union is ({1,2,5,6}). It shows the parts outside the common part.
Exam Tip
(A-B={1,2}) और (B-A={5,6}), इसलिए संघ ({1,2,5,6}) है। यह सामान्य भाग को छोड़कर बचे भागों को दिखाता है।
