As shown in the given image, each part of the dice has been marked with 6 letters G, H, I, J, K and L. Which letter is in the opposite part of I?

The logic followed here is :-

From the given two different cubes the adjacent sides are as shown below :

As J is common on both the dice, it is clear that G, I, L and K are adjacent to it and remaining number i.e., H will be opposite to it.

Opposite pairs:

G → L

I → K

H → J

So, the opposite side of "I" will be side "K".

Hence, the correct answer is "K".
