Which number will appear on the face opposite to 1?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 3
Faces seen together in one view are neighbours, and a face is never a neighbour of the face opposite it. So the neighbours of a number rule out its opposite face.
From the two views, 2 touches 4, 3 and 1, so the face opposite 2 is 5 or 6
In the same way, 4 touches 2, 3 and 1, so the face opposite 4 is the other of 5 and 6
2, 4, 5 and 6 thus make up two opposite pairs, and the remaining two numbers form the third pair: 3 is opposite 1
Tip: When two views of a die show two common numbers in the same positions, the remaining numbers of the two views lie on opposite faces; here 2 and 4 are common, so 3 and 1 are opposite.
