यदि \(A=\{1,2,3,4,5,6\}\) और (R={(a,b):\(a\equiv b \pmod{3}\)}) है तो कितने तुल्यता वर्ग बनेंगे?
If \(A=\{1,2,3,4,5,6\}\) and (R={(a,b):\(a\equiv b \pmod{3}\)}), how many equivalence classes are formed?
Explanation opens after your attempt
B. (3)
Concept
Modulo (3) gives the remainders (0,1,2). Hence (3) equivalence classes are formed.
Why this answer is correct
The correct answer is B. (3). Modulo (3) gives the remainders (0,1,2). Hence (3) equivalence classes are formed.
Exam Tip
मापांक (3) के अनुसार शेषफल (0,1,2) होते हैं। इसलिए (3) तुल्यता वर्ग बनते हैं।
