यदि \(A\subseteq B\), \(B\subseteq C\), और \(A\not=C\) है तो कौन सा कथन हमेशा सत्य है?
If \(A\subseteq B\), \(B\subseteq C\), and \(A\not=C\), which statement is always true?
Explanation opens after your attempt
Correct Answer
A. \(A\subset C\) उचित रूप से(A) is a proper subset of (C)
Concept
By transitivity \(A\subseteq C\), and since \(A\ne C\), (A) is a proper subset. The middle set may or may not be equal.
Why this answer is correct
The correct answer is A. \(A\subset C\) उचित रूप से / (A) is a proper subset of (C). By transitivity \(A\subseteq C\), and since \(A\ne C\), (A) is a proper subset. The middle set may or may not be equal.
Exam Tip
ट्रांजिटिव नियम से \(A\subseteq C\) और \(A\not=C\) होने से (A) उचित उपसमुच्चय है। बीच वाला समुच्चय बराबर भी हो सकता है।
