Six letters P, Q, R, S, T, and U are written on different faces of a dice. Two positions of this dice are shown in the figure below. Find the letter on the face opposite to R.

Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. S.
The figure is rotated in a clockwise direction from the common letter R.
Opposite Pairs:
| Dice 1 | R | P | T |
| Dice 2 | R | Q | U |
P ⇔ Q, T ⇔ U, So, the remaining side S is opposite to R.
Hence, S is the opposite face of R.
