    If\[\Delta =\]and \[p\square qOr,\]then

    A)  \[p\phi q\square r\]

    B)  \[p\phi q\times r\]

    C)  \[p+q\times r\]

    D)  \[p\Delta q\phi r\]

    Correct Answer: B

    Solution :

        \[2C<A+E,A+E=C+D\] \[\Rightarrow \] \[2C<C+D\]\[\Rightarrow \]\[C<D\]             ??(1) \[A+D=B+C,C<D\] \[\Rightarrow \] \[A<B\]           ??(2) \[2A>B+D,A<B\]\[\Rightarrow \]\[A>D\]                 ??(3) \[A+E=C+D,A>D\]\[\Rightarrow \]\[E<C\]             ??(4)
