    If \['\beta '\] means 'equal to, \['\delta '\]means "not equal to' and \['\eta '\] means 'not greater than', then which of the following four could be a correct inference in \[2A\delta B\text{ }and\text{ }B\beta 3C?\]

    A) \[2A\delta 3C\]              

    B) \[6C\eta B~\]                

    C) \[B\delta 6A~\]             

    D) \[2A\eta 3C\]

    Correct Answer: A

    Solution :

    : \[2A\delta B\Rightarrow 2A\cancel{=}B\] and \[B\beta 3C\Rightarrow B=3C\] \[\Rightarrow 2A\ne 3C\Rightarrow 2A\delta 3C.\]
