Kristina has a piece of transparent paper with some lines marked on it. She folds it along the central dashed line, as indicated. What can she now see?
C
Each digit in the completed number contains three horizontal line segments. Since the markings above the fold will appear the other way up when folded, the first digit in the completed number contains a vertical line top left and a vertical line bottom right in addition to the three horizontal lines and so is a 5. The second digit in the completed number contains a double length vertical line on the left and a vertical line bottom right in addition to the three horizontal lines and so is a 6.
Similarly, the third digit in the completed number contains a double length vertical line on the right and a vertical line top left in addition to the three horizontal lines and so is a 9. Therefore the number that will be seen is 569.
