Paper cutting, folding and punching — Practice MCQs

In paper folding and punching, a sheet is folded, punched, and then unfolded. You have to predict where the holes appear. Every fold doubles the number of holes.

Method

1. Unfold in reverse order: undo the last fold first.
2. For each fold, copy every hole as a mirror image across the fold line.
3. Count: k folds and h holes punched give h × 2^k holes, unless a hole sits exactly on a fold line.

Quick checks on the options

• A vertical fold makes the pattern symmetric left to right. A horizontal fold makes it symmetric top to bottom.
• Rule out any option with the wrong number of holes or without the required symmetry.
