Three different positions of the same dice are given below. Find the number opposite of 7.

Correct option is D

Given:

Logic: If two dice show the same face value, then the numbers adjacent to that face on both dice are considered opposite.
In the first and second dice, the number 3 is common. The numbers adjacent to 3 on both dice, when observed in a clockwise direction, will be opposite each other.
3 8 12
3 20 15
3 will come on the face opposite to the face containing '7' on.
Correct answer is (d).
