Using Statement-I alone: Statement-I tells us that $x/y$ is odd, meaning the quotient of $x$ and $y$ is an odd number. For this to be true, $x$ must be an odd multiple of $y$. However, without knowing any specific values for $x$ and $y$, we cannot conclude the exact values of $x$ and $y$. Therefore, Statement-I alone is insufficient to answer the question.

Using Statement-II alone: Statement-II states that $xy = 12$. The factors of 12 are $(1, 12)$, $(2, 6)$, $(3, 4)$, $(12, 1)$, $(6, 2)$, $(4, 3)$. These are the only possible pairs of $x$ and $y$ that satisfy the equation $xy = 12$. However, we still need more information to determine the unique values of $x$ and $y$. Therefore, Statement-II alone is insufficient to answer the question.

Combining Statement-I and Statement-II: From Statement-II, we know the possible pairs of $(x, y)$ that satisfy $xy = 12$ are $(1, 12)$, $(2, 6)$, $(3, 4)$, $(12, 1)$, $(6, 2)$, $(4, 3)$.

• Only for the pair $(6, 2)$, $x/y = 6/2 = 3$ is odd.

Thus, the only pair that satisfies both the condition $xy = 12$ and $x/y$ being odd is $(6, 2)$. Therefore, combining both statements, we can conclude that the unique values of $x$ and $y$ are 6 and 2.
