This topic tests your ability to visualize how a piece of paper will look after it is folded, cut, and then unfolded. The key is to understand the Line of Symmetry created by the fold.
When a paper is unfolded, the pattern of cuts/holes appears symmetrically across the fold line. It acts like a Mirror Image.
Total Holes = (Number of Holes Punched) ├Ч (Number of Layers at that spot).
Example: If a paper is folded twice (4 layers) and one hole is punched, the unfolded paper will have 4 holes.
X represents Original Sheet -> Y represents Folded Sheet -> Z represents Cut Sheet.
You must reverse the process from Z to X to find the answer.
