Two positions of the same cubical block are shown. When '6' is at the top, which number will be at the bottom?

Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 4.
In both dice, 4 is common. So, start rotating either in the clockwise or anticlockwise direction.
Clockwise direction:
Dice 1: 4 5 2
Dice 2: 4 3 1
So, 4 is opposite to 6.
