A dice has its faces marked by letters N, R, P, I, T and E. Two positions of the same dice are shown in the given figures. Which face is opposite to face E?

Logic: As N is the common face on both the dice, keeping it constant and then rotating in clockwise/anti clockwise direction, we get the faces opposite to each other:
Common face is opposite to hidden face.
N---R---I
N---T---P
Here,
N ⟷ E (Hidden Face) → From Options
R ⟷ T
I ⟷ P
Therefore, N on the face opposite to E.
Thus, the correct option is (a) N.​​
