यदि \(A=\{1,2,3,4,5,6\}\), \(B=\{2,4,6,8\}\) और \(C=\{1,2,8,9\}\), तो \((A-B)\cup(A-C)\) क्या है?
If \(A=\{1,2,3,4,5,6\}\), \(B=\{2,4,6,8\}\), and \(C=\{1,2,8,9\}\), what is \((A-B)\cup(A-C)\)?
Explanation opens after your attempt
A. ({1,3,4,5,6})
Concept
(A-B={1,3,5}) and (A-C={3,4,5,6}). Their union is ({1,3,4,5,6}).
Why this answer is correct
The correct answer is A. ({1,3,4,5,6}). (A-B={1,3,5}) and (A-C={3,4,5,6}). Their union is ({1,3,4,5,6}).
Exam Tip
(A-B={1,3,5}) और (A-C={3,4,5,6}) है। इनका संघ ({1,3,4,5,6}) है।
