A) 2 B) 3
C) 6 D) Cannot be determined
 
Answer & Explanation Answer: A) 2

(i) i.e. on RHS face (i.e. on face II as per activity 1) and 1 dot appears at the same position as in fig; (i) i.e. on Front face (i.e. on face I). Then, from the, two figures, 2 dots appear on the top face (i.e. on face V) and 4 dots appear on the Bottom face (i.e. on face VI).

 

Since, these two faces are opposite to each other, therefore, two dots are contained on the face opposite to that containing four dots.
