Question
Two different positions of same dice are shown, the
faces of which are marked with letters A, B, C, D, E and F. Select the letter that will be on the face opposite to the face having letter ‘A’.Solution
In such questions, first consider common side in both dice. Here, letter ‘E’ is common. In clockwise direction, the sequence will be (E, D, and B) in dice (a). In clockwise direction, the sequence will be (E, C, and A) in dice (b). Clearly, B is opposite to A.
