Question
Six letters T, F, J, B, S, and V are written on
different faces of a dice. Two positions of this dice are shown in the figures below. Find the letter on the face opposite to S.Solution
In (a) and (b) figure, common letter is 'S' so, In clockwise direction, the sequence will be (S, T, J) in figure (a) . In clockwise direction, the sequence will be (S, F, B) in figure (b) . So, we get, 'T' is opposite to 'F', 'J' is opposite to 'B'. So, clearly, 'S' is opposite to 'V'
