    If A + D = B + C, A + E = C + D, 2C < A + E and 2A > B + D, then

    A) A > B > C > D > E

    B) B > A > D > C > E

    C) D > B > C > A > E

    D) B > C > D > E > A

    Correct Answer: B

    Solution :

         \[2C<A+E,A+E=C+D\] \[\Rightarrow 2C<C+D\Rightarrow C<D\]               .......... (a) \[A+D=B+C,C<D\Rightarrow A<B\]          .......... (b) \[2A>B+D,A<B\Rightarrow A>D\]              .......... (c) \[A+E=C+D,A>D\Rightarrow E<C\]          .......... (d)
