यदि \(A\subseteq B\), (n(A)=6), और (n(B)=6) है तो (A) और (B) के बारे में क्या निश्चित है?
If \(A\subseteq B\), (n(A)=6), and (n(B)=6), what is certain about (A) and (B)?
Explanation opens after your attempt
A. (A=B)
Concept
When \(A\subseteq B\) and both have the same number of elements, no extra element remains. Hence (A=B).
Why this answer is correct
The correct answer is A. (A=B). When \(A\subseteq B\) and both have the same number of elements, no extra element remains. Hence (A=B).
Exam Tip
जब \(A\subseteq B\) और दोनों के अवयवों की संख्या समान हो तो कोई अतिरिक्त अवयव नहीं बचता। इसलिए (A=B)।
