समुच्चय \(\mathbb{Z}\) पर (aRb) तभी जब (a-b) संख्या (4) से विभाज्य हो। इस relation द्वारा कितने equivalence classes बनते हैं?
On \(\mathbb{Z}\), (aRb) if and only if (a-b) is divisible by (4). How many equivalence classes are formed by this relation?
Explanation opens after your attempt
A. (4)
Concept
The remainders (0,1,2,3) form (4) different classes. For a modulo relation, the number of classes equals the modulus.
Why this answer is correct
The correct answer is A. (4). The remainders (0,1,2,3) form (4) different classes. For a modulo relation, the number of classes equals the modulus.
Exam Tip
शेषफल (0,1,2,3) के अनुसार (4) अलग classes बनती हैं। Modulo relation में classes की संख्या modulus के बराबर होती है।
