    Let R be a relation on N defined by \[x+2y=8.\]The domain of R is

    A) \[\{2,4,8\}\]

    B)        \[\{2,4,6,8\}\]

    C) \[\{2,4,6\}\]

    D)        \[\{1,2,3,4\}\]

    Correct Answer: C

    Solution :

    [c]  R be a relation on N defined by \[x+2y=8\] \[\therefore R=\{(2,3);(4,2);(6,1)\}\] Hence, Domain of \[R=\{2,4,6\}\]
