\(A=\{1,2,3,4,5,6\}\) पर (aRb) यदि \(a \equiv b \pmod{2}\)। तुल्यता वर्गों की संख्या कितनी है?
On \(A=\{1,2,3,4,5,6\}\), (aRb) if \(a \equiv b \pmod{2}\). How many equivalence classes are there?
Explanation opens after your attempt
Correct Answer
B. (2)
Concept
Even and odd numbers form two separate classes. Under \( \pmod{2}\), only (2) remainders are possible.
Why this answer is correct
The correct answer is B. (2). Even and odd numbers form two separate classes. Under \( \pmod{2}\), only (2) remainders are possible.
Exam Tip
सम और विषम दो अलग वर्ग बनते हैं। \( \pmod{2}\) में केवल (2) शेषफल संभव हैं।
