A piece of paper is folded and cut as shown below. From the given figures, indicate how it will appear when it is opened?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) →
The circle is folded twice (into a half, then a quarter), so the cut passes through four layers of paper and every cut appears four times when the sheet is opened, once in each quarter.
One notch on the curved edge of the quarter gives 4 notches round the rim
Two small holes give \(2\times4=\) 8 holes, and nothing is cut at the centre
Only Option (4) has four notches and eight holes with a plain centre; the other figures show extra notches or a cut-out at the centre.
