Two different positions of the same dice marked with the letters a, b, c, d, e, and f are shown. Select the letter that will be on the face opposite to the face having the letter 'a'.

Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. f.
In both the dice, e is common. So, start rotating either in the clockwise or anticlockwise direction.
Clockwise direction:
Dice 1: e d a
Dice 2: e b f
So, a is opposite to f.
Anticlockwise direction:
Dice 1: e a d
Dice 2: e f b
So, a is opposite to f.
Hence, option 4 is the correct answer.
