Choose 2 ; if the question can be answered by using either statement alone.
Choose 3 ; if the question can be answered by using both statements together, but cannot be answered using either statement alone.
Choose 4 ; if the question cannot be answered even by using both statements together.
Consider three real numbers, X, Y and Z. Is Z the smallest of these numbers?
X is greater than at least one of Y and Z.
Y is greater than at least one of X and Z.
From statement A, there are four possibilities.
∴ This statement alone is not sufficient.
From statement B, there are four possibilities.
∴ This statement alone is not sufficient.
In both the cases Z is smallest.
Hence, option (c).
