A square sheet of filter paper is folded in half from left to right, then folded in half from top to bottom. A single circular hole is punched through all layers near the folded corner (center of the original sheet). When completely unfolded, how many holes appear?
Options:
(A) 4 holes forming a central cluster
(B) 2 holes along the crease
(C) 1 hole at the center
(D) 8 holes in a circle
Answer Key:
C
Step-by-Step Solution & Explanation
Because the punch is made precisely at the folded corner corresponding to the geometric center of the sheet, all four quadrants share this single vertex, resulting in 1 single hole at the center.
