Question

A dice is numbered from $1$ to $6$ in different ways.
If $1$ is adjacent to $2,4$ and $6$, then which of the following statements is necessarily true?

• A. $2$ is opposite to $6$
• B. $1$ is adjacent to $3$
• C. $3$ is adjacent to $5$
• D. $3$ is opposite to $5$

Answer 1

The correct option is C $3$ is adjacent to $5$

If $1$ is adjacent to $2,4$ and $6$ then either $3$ or $5$ lies opposite to $1$. So, the numbers $3$ and $5$ cannot lie opposite to each other. Hence, $3$ is adjacent to $5$ (necessarily).
