यदि \(A=\{r,s,t,u\}\), \(B=\{s,u,v\}\) और \(C=\{u,v,w\}\) हैं, तो (A\cap\(B\cup C\)) क्या है?

If \(A=\{r,s,t,u\}\), \(B=\{s,u,v\}\), and \(C=\{u,v,w\}\), what is (A\cap\(B\cup C\))?

Explanation opens after your attempt
Correct Answer

A. ( {s,u} )

Step 1

Concept

First \(B\cup C={s,u,v,w}\). Its common part with (A) is ({s,u}).

Step 2

Why this answer is correct

The correct answer is A. ( {s,u} ). First \(B\cup C={s,u,v,w}\). Its common part with (A) is ({s,u}).

Step 3

Exam Tip

पहले \(B\cup C={s,u,v,w}\) है। इसका (A) से सामान्य भाग ({s,u}) है।
