Q.4
A circular sheet of paper is folded along the lines in the directions shown.
The paper, after being punched in the final folded state as shown and
unfolded in the reverse order of folding, will look like _______.
Paper Folding and Punching Aptitude Question – Full Solution
This question shows a circular sheet of paper being folded twice and punched.
We must unfold the sheet in reverse and identify the final pattern.
Understanding the Folds
-
First fold: The circle is folded in half vertically.
-
Second fold: The semicircle is folded again horizontally.
Now the paper is ¼ of its original circle.
Punching Pattern
Two types of cuts are made on the folded quadrant:
-
Rectangular punches
-
A circular punch at the center edge fold
When unfolded, every punch replicates symmetrically based on the number of folds:
-
2 folds → punch appears 4 times
-
Central cut becomes circular hole at center
Correct Answer: (C) ✔️
Option-wise Explanation
Option (A) ❌
-
Shows correct number of central holes but wrong placement of rectangles.
-
Rectangular slits are not evenly spaced at 90° intervals.
-
Mismatch with unfolding symmetry.
Option (B) ❌
-
Misplaces the rectangular punches.
-
Opposite positions do not align radially.
-
Symmetry of four reflections is missing.
Option (C) ✔️
-
Shows:
-
One central circular hole split into four arcs → becomes a full circle at the center.
-
Four rectangular punches evenly spaced at 90° → correct replication of punching.
-
-
Matches the fold symmetry exactly.
-
Correct representation after unfolding.
Option (D) ❌
-
Punches placed only in three quadrants.
-
Missing one reflected slit.
-
Not possible because every punch in folded state duplicates in all four quadrants.
Final Answer
✔️ The correct unfolded figure is Option (C).
Conclusion
Paper folding and punching questions can be solved by tracking folds and applying symmetry.
Every fold doubles the number of punch marks, and correct unfolding maintains radial geometry.
