If $A, B, C, D$ are numbers in increasing order and $D, B, E$ are numbers in decreasing order, then which one of the following sequences need neither be in a decreasing nor in an increasing order?
(a)$E, C, D$
(b)$E, B, C$
(c)$D, B, A$
(d)$A, E, C$
Answer
Answer (as printed): D
Explanation
$A<B<C<D \Rightarrow D>B>A$ Also, $A<B<C<D$ and $D>B>E \Rightarrow E<B<C<D$ $\Rightarrow E<C<D$ and $E<B<C$. Clearly, we cannot arrange $A, E, C$ is an increasing or decreasing order.
