यदि \(A=\{1,2,3,4,5\}\), \(B=\{1,3,5\}\) और \(C=\{0,2\}\) हैं, तो \((A-B)\times C\) में कितने अवयव होंगे?

If \(A=\{1,2,3,4,5\}\), \(B=\{1,3,5\}\) and \(C=\{0,2\}\), how many elements are there in \((A-B)\times C\)?

Explanation opens after your attempt
Correct Answer

A. (4)

Step 1

Concept

(A-B={2,4}), so (n\((A-B)\times C\)=2\times2=4). It is necessary to find the set difference first.

Step 2

Why this answer is correct

The correct answer is A. (4). (A-B={2,4}), so (n\((A-B)\times C\)=2\times2=4). It is necessary to find the set difference first.

Step 3

Exam Tip

(A-B={2,4}), इसलिए (n\((A-B)\times C\)=2\times2=4)। पहले समुच्चय अंतर निकालना जरूरी है।
