A paper is folded and cut as shown below. How will it appear when unfolded?

Correct — C. Undo the folds in reverse order, and watch which cuts sit on a fold.

Right half onto left, then top onto bottom: the cut quarter is the bottom-left one, and its top and right edges are the fold lines.

Rule: a cut touching a fold opens across it; a cut clear of every fold repeats once per layer.

Square, hanging from the top edge → one tall rectangle across the horizontal fold, and its copy on the right.
Triangle, drawn near the right edge but clear of it → four copies, and since every unfold mirrors, each row holds a facing pair.
Oval, touching nothing → four copies.

That is option (c).

Why the others are wrong

• (a)
  Four separate small squares, and triangle pairs whose points face outward. The first fault ignores the fold the square hangs from; the second forgets that every unfold is a mirror.
• (b)
  Four separate small squares where the answer needs two tall rectangles — this is the picture you would get if the cut square hung clear of the horizontal fold instead of from it.
• (d)
  Rectangles and ovals are right, but the two triangles in each row point the same way. An unfold is a reflection, so the copy must face back at the original.

Paper-folding items are read backwards. Note the order of the folds, then undo the last one first; each undo reflects everything you have so far across that fold line.

How many copies a cut yields depends on where it sits. A cut clear of every fold appears once per layer, so two folds give four layers and four copies. A cut touching a fold has its own mirror joined to it along that line, so the two copies fuse into one larger shape and the total drops.

Key facts

• Two folds make four layers, so a cut clear of both fold lines opens into four copies.
• A cut sitting on a fold line opens into one shape symmetric about that line, not two separate shapes.
• Every unfold is a reflection, so a shape and its copy face each other across the fold.

Common traps

• Undoing the folds in the order they were made instead of in reverse
• Counting four copies of a cut that is sitting on a fold line
• Copying a shape across a fold without mirroring it
