Question

A sheet of paper is folded along the white dotted lines and then cut along black dotted lines as depicted below. Out of the four scaled down options, which is the CORRECT resultant unfolded paper? 

 

• A. A
• B. B
• C. C
• D. D

Hint:

For folding and cutting problems, visualize the sequence of operations carefully to determine the final shape or pattern after unfolding.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
The strip is folded accordion-style into equal panels, and a single diagonal cut is made near one folded edge before the strip is opened back out.

Step 2: Key Formula or Approach:
Work out what the cut looks like on just one panel, then repeat that exact same shape, size, and spacing across every other panel in the unfolded strip, since every panel was folded from the same stack and cut at the same time.

Step 3: Detailed Explanation:
Building the expected result this way and comparing it with the options shows that A has one oversized diamond, B has one diamond at the wrong height, and D is missing a diamond in one panel, each breaking the single-panel-repeated-exactly rule. Option C repeats the same diamond shape, size and spacing across every panel with no exceptions.

Step 4: Final Answer:
Option C is the correctly and consistently repeated unfolded pattern.

Answer 2

A quick check before looking at exact shapes is to count how many diamond cut-outs appear in total across the strip, since the number of folded panels fixes exactly how many repeats of the cut there should be.

1. Option A: The total count of diamonds matches, but one of them is a different size from the rest, which a single repeated cut across identical panels would not produce.
2. Option B: The total count matches, but one diamond sits at an inconsistent height compared with the others.
3. Option C: The total count of diamonds matches the number of panels, and every diamond is the same size and sits at the same alternating height as the rest.
4. Option D: The total count comes up short, since one panel is missing its diamond entirely.

Counting the diamonds and then checking their size and spacing confirms option C as the only fully consistent result.

So the correct answer is Option C.
