यदि \(A\subseteq B\) और (n(A)=n(B)) है, जहाँ दोनों सीमित समुच्चय हैं, तो क्या निष्कर्ष है?
If \(A\subseteq B\) and (n(A)=n(B)), where both sets are finite, what follows?
Explanation opens after your attempt
Correct Answer
A. (A=B)
Concept
For finite sets, if a subset has the same number of elements, no extra element remains. Therefore the sets are equal.
Why this answer is correct
The correct answer is A. (A=B). For finite sets, if a subset has the same number of elements, no extra element remains. Therefore the sets are equal.
Exam Tip
सीमित समुच्चयों में उपसमुच्चय की सदस्य संख्या बराबर हो तो कोई अतिरिक्त सदस्य नहीं बचता। इसलिए समुच्चय बराबर हैं।
