यदि \(U=\{a,b,c,d,e,f,g,i\}\), \(A=\{a,c,f\}\) और \(B=\{b,c,e,i\}\), तो (\(A\cup B\)') क्या है?
If \(U=\{a,b,c,d,e,f,g,i\}\), \(A=\{a,c,f\}\), and \(B=\{b,c,e,i\}\), what is (\(A\cup B\)')?
Explanation opens after your attempt
A. ({d,g})
Concept
First form \(A\cup B={a,b,c,e,f,i}\). Removing it from (U) gives ({d,g}).
Why this answer is correct
The correct answer is A. ({d,g}). First form \(A\cup B={a,b,c,e,f,i}\). Removing it from (U) gives ({d,g}).
Exam Tip
पहले \(A\cup B={a,b,c,e,f,i}\) बनाएं। इसे (U) से हटाने पर ({d,g}) मिलता है।
