    If R be a relation from set A to B defined by \[xRy\Rightarrow \left( x-y \right)\] is positive then R is. If \[A=\left\{ 4,3 \right\},\text{ }B=\left\{ 2,3,4 \right\}-\]

    A) \[R=\left\{ \left( 4,\text{ }2 \right),\text{ }\left( 4,3 \right),\text{ }\left( 3,2 \right) \right\}\]

    B) \[R=\left\{ \left( 4,3 \right),\left( 3,4 \right) \right\}\]

    C) \[R=\left\{ \left( 2,3 \right),\left( 2,5 \right) \right\}\]

    D)  \[r=\phi \]

    Correct Answer: A

    Solution :

    [a] \[R:A\to B\] where \[xRy\Rightarrow x-y\] is positive i.e. \[x-y>0\Rightarrow x>y\]
