Single Digit Water Image
Single Digit Water Image problems involve digits that transform when viewed as water images. Digits like 0, 1, and 8 remain the same, while 6 becomes 9 and 9 becomes 6 in water reflection. These problems test your knowledge of how digits appear when reflected vertically.

Introduction to Single Digit Water Image
Single Digit Water Image problems involve digits that transform when viewed as water images. Digits like 0, 1, and 8 remain the same, while 6 becomes 9 and 9 becomes 6 in water reflection. These problems test your knowledge of how digits appear when reflected vertically.
Prerequisites
How to Solve Single Digit Water Image Problems
Step 1: Identify the given digit
Step 2: Imagine the digit reflected vertically (upside down)
Step 3: For digit 0, water image remains 0
Step 4: For digit 1, water image remains 1
Step 5: For digit 8, water image remains 8
Step 6: For digit 6, water image becomes 9
Step 7: For digit 9, water image becomes 6
Step 8: For other digits (2,3,4,5,7), water images are not defined or ambiguous
Example Problem
Example: What is the water image of the digit '6'? Solution: Step 1: Given digit: 6 Step 2: When reflected vertically, 6 transforms into 9 Step 3: The circular part of 6 becomes the circular part of 9 Step 4: The tail of 6 becomes the tail of 9 (but on opposite side) Step 5: Therefore, water image of 6 is 9 Answer: 9
Pro Tips & Tricks
- Digit 0 looks same in water image (perfect circle)
- Digit 1 looks same (vertical line remains vertical)
- Digit 8 looks same (symmetrical figure)
- Digit 6 becomes 9, and 9 becomes 6
- Digit 2,3,4,5,7 have no defined water images (they look different and are rarely tested)
- Write the digit on paper and rotate 180 degrees to visualize water image
