यदि \(A\subseteq B\), (n(A)=4), और (n(B)=10), तो (n\(A\cap B\)) क्या है?

If \(A\subseteq B\), (n(A)=4), and (n(B)=10), what is (n\(A\cap B\))?

Explanation opens after your attempt
Correct Answer

A. (4)

Step 1

Concept

When \(A\subseteq B\), \(A\cap B=A\), so the number is (4). The entire inner set becomes the common part.

Step 2

Why this answer is correct

The correct answer is A. (4). When \(A\subseteq B\), \(A\cap B=A\), so the number is (4). The entire inner set becomes the common part.

Step 3

Exam Tip

जब \(A\subseteq B\), तब \(A\cap B=A\), इसलिए संख्या (4) है। अंदर वाला पूरा समुच्चय साझा भाग बनता है।
