यदि (R) और (S) दोनों संक्रामी संबंध हैं, तो \(R \cap S\) के बारे में कौन-सा कथन सही है?
If (R) and (S) are both transitive relations, which statement about \(R \cap S\) is correct?
Explanation opens after your attempt
A. \(R \cap S\) हमेशा संक्रामी होता है\(R \cap S\) is always transitive
Concept
यदि ((a,b)) और ((b,c)) दोनों \(R \cap S\) में हैं, तो वे (R) और (S) दोनों में होंगे। / If ((a,b)) and ((b,c)) are in \(R \cap S\), they are in both (R) and (S).
Why this answer is correct
दोनों संक्रामी हैं, इसलिए ((a,c)) भी दोनों में होगा। / Since both relations are transitive, ((a,c)) is in both.
Exam Tip
अतः ((a,c)), \(R \cap S\) में होगा। / Therefore, ((a,c)) is in \(R \cap S\), so the intersection is transitive.
