JEE Main & Advanced Mathematics Sets Question Bank Relations

  • question_answer
    Let A = {1, 2, 3, 4} and let R= {(2, 2), (3, 3), (4, 4), (1, 2)} be a relation on A. Then R is

    A) Reflexive

    B) Symmetric

    C) Transitive

    D) None of these

    Correct Answer: C

    Solution :

    Since (1, 1)\[\not{\in }R\]so, is not reflexive. Now (1, 2) \[\in R\]but (2,1) \[\not{\in }R\], therefore R is not symmetric Clearly R is transitive.
