Select the option that correctly explains the folding and punching of the paper shown in the given figure.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) →
The square sheet is folded twice into a quarter (the solid square in each option), and a hole punched through the folded sheet goes through all four layers. When the sheet is opened, each hole appears in all four quarters, reflected in the fold lines.
The opened sheet has, in every quarter, one hole at its outer corner and one hole next to the centre of the sheet. So the folded quarter must have just two holes: one at its outer corner and one at the corner next to the centre, as in Option (3).
