यदि \(A=\{1,2,3,4,5,6\}\) पर (aRb) यदि \(a\equiv b \pmod{3}\) हो तो (1) के तुल्यता वर्ग में क्या होगा?
If on \(A=\{1,2,3,4,5,6\}\), (aRb) if \(a\equiv b \pmod{3}\), what is the equivalence class of (1)?
Explanation opens after your attempt
Correct Answer
B. \({1,4}\)
Concept
Both (1) and (4) leave remainder (1) when divided by (3). Therefore the class of (1) is ({1,4}).
Why this answer is correct
The correct answer is B. \({1,4}\). Both (1) and (4) leave remainder (1) when divided by (3). Therefore the class of (1) is ({1,4}).
Exam Tip
(1) और (4) को (3) से भाग देने पर शेष (1) मिलता है। इसलिए (1) का वर्ग ({1,4}) है।
