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

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

Explanation opens after your attempt
Correct Answer

A. ({(1,2),(1,4),(3,2),(3,4),(5,2),(5,4)})

Step 1

Concept

(B-C={2,4}), so \(A\times(B-C)\) has (6) pairs. In set difference, keep only elements remaining from (B).

Step 2

Why this answer is correct

The correct answer is A. ({(1,2),(1,4),(3,2),(3,4),(5,2),(5,4)}). (B-C={2,4}), so \(A\times(B-C)\) has (6) pairs. In set difference, keep only elements remaining from (B).

Step 3

Exam Tip

(B-C={2,4}), इसलिए \(A\times(B-C)\) में (6) युग्म हैं। अंतर में केवल (B) के बचे अवयव लें।
