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

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

Explanation opens after your attempt
Correct Answer

A. ( {1,4} )

Step 1

Concept

\(B\cup C={2,3,5,6,7}\), and removing these from (A) leaves ({1,4}). Solve the bracket first.

Step 2

Why this answer is correct

The correct answer is A. ( {1,4} ). \(B\cup C={2,3,5,6,7}\), and removing these from (A) leaves ({1,4}). Solve the bracket first.

Step 3

Exam Tip

\(B\cup C={2,3,5,6,7}\) है और (A) से इन्हें हटाने पर ({1,4}) बचता है। पहले कोष्ठक हल करें।
