One die is drawn below in two different ways. Find the number opposite 9.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 8
A face of a die touches four other faces and is opposite the one face it never touches. Faces seen together in one picture are neighbours, so they can never be opposite each other.
9 is seen next to 1 and 4 in (i); 2 and 5 in (ii). So 9 touches four faces, and the only face left, 8, is opposite 9
Why the other options are incorrect
Option (1) 2 — Incorrect. 2 is seen next to 9 in picture (ii), so it touches 9 and cannot be opposite it.
Option (3) 1 — Incorrect. 1 is seen next to 9 in picture (i), so it touches 9 and cannot be opposite it.
Option (4) 5 — Incorrect. 5 is seen next to 9 in picture (ii), so it touches 9 and cannot be opposite it.
