यदि \(A=\{1,2,5,7\}\), \(B=\{2,4,6\}\) और \(C=\{5,6,8\}\) हैं, तो (A\cap \(B\cup C\)) क्या है?

If \(A=\{1,2,5,7\}\), \(B=\{2,4,6\}\), and \(C=\{5,6,8\}\), what is (A\cap \(B\cup C\))?

Explanation opens after your attempt
Correct Answer

A. ( {2,5} )

Step 1

Concept

First find \(B\cup C={2,4,5,6,8}\). Then the common elements with (A) are (2) and (5).

Step 2

Why this answer is correct

The correct answer is A. ( {2,5} ). First find \(B\cup C={2,4,5,6,8}\). Then the common elements with (A) are (2) and (5).

Step 3

Exam Tip

पहले \(B\cup C={2,4,5,6,8}\) निकालें। फिर (A) से सामान्य अवयव (2) और (5) मिलते हैं।
