Class 11 Mathematics Sets Operations on Sets (Union, Intersection, Difference) Medium Level 18

यदि \(A=\{2,4,6,8,10\}\), \(B=\{1,2,3,4,5\}\) और \(C=\{4,5,6,7\}\) है, तो (A\cap\(B\cup C\)) क्या है?

If \(A=\{2,4,6,8,10\}\), \(B=\{1,2,3,4,5\}\), and \(C=\{4,5,6,7\}\), what is (A\cap\(B\cup C\))?

Explanation opens after your attempt
Correct Answer

A. ( {2,4,6} )

Step 1

Concept

First \(B\cup C={1,2,3,4,5,6,7}\). Its intersection with (A) is ({2,4,6}).

Step 2

Why this answer is correct

The correct answer is A. ( {2,4,6} ). First \(B\cup C={1,2,3,4,5,6,7}\). Its intersection with (A) is ({2,4,6}).

Step 3

Exam Tip

पहले \(B\cup C={1,2,3,4,5,6,7}\) है। इसका (A) से प्रतिच्छेद ({2,4,6}) है।
