Question

Two positions of a dice with $1$ to $6$ dots on its sides are shown below. If the dice is resting on the side with three dots, what will be number of dots on the side at the top?

• A. $1$ or $5$
• B. $2$
• C. $3$
• D. $5$

Answer 1

Answer: (A)

$1$ or $5$

From figures (i) and (ii) we conclude that $2,6$ and $4$ dots appear adjacent to $3$ dots. Hence, either $1$ or $5$ dots may appear opposite $3$ dots. Thus, if the dice is resting on the side with three dots, then the number of dots on the side at the top is either $1$ or $5$.
