यदि \(U=\{p,q,r,s,t,u,v\}\), (A'={q,s,u}) और \(B=\{p,q,t,v\}\), तो \(A\cap B\) क्या है?

If \(U=\{p,q,r,s,t,u,v\}\), (A'={q,s,u}), and \(B=\{p,q,t,v\}\), what is \(A\cap B\)?

Explanation opens after your attempt
Correct Answer

A. ({p,t,v})

Step 1

Concept

First write (A=U-A'={p,r,t,v}). Intersecting with (B) gives ({p,t,v}).

Step 2

Why this answer is correct

The correct answer is A. ({p,t,v}). First write (A=U-A'={p,r,t,v}). Intersecting with (B) gives ({p,t,v}).

Step 3

Exam Tip

पहले (A=U-A'={p,r,t,v}) लिखें। फिर (B) से प्रतिच्छेद लेने पर ({p,t,v}) मिलता है।
