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

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

Explanation opens after your attempt
Correct Answer

B. (4)

Step 1

Concept

(A-B={1,2}) and (B-A={5,6}). Hence (n(A-B)+n(B-A)=2+2=4).

Step 2

Why this answer is correct

The correct answer is B. (4). (A-B={1,2}) and (B-A={5,6}). Hence (n(A-B)+n(B-A)=2+2=4).

Step 3

Exam Tip

(A-B={1,2}) और (B-A={5,6}) है। इसलिए (n(A-B)+n(B-A)=2+2=4)।
