Two positions of a block are shown below: When six is at the bottom, what number will be at the top?

A) 1

B) 2

C) 4

D) 5

Answer: D) 5

Explanation:

From figures (i) and (ii) we conclude that the number 1, 2, 3 and 4 appear adjacent to 6. Thus, the number 5 will appear opposite 6. Therefore, when six is at the bottom, then 5 will be at the top.
