Mirror and Water Images for SSC CGL
Master Reflection and Reversal Logic
1. Introduction
Mirror and Water Images are a key part of SSC CGL Non-Verbal Reasoning. These questions test your ability to visualize reflections and reversals.
These questions are scoring because with practice, you can quickly identify patterns and orientations.
2. Definition
Mirror Image: When an object or figure is reflected in a mirror, the left and right sides are swapped.
Water Image: When an object or figure is reflected in water, the top and bottom are reversed.
Example: Original: ABC
Mirror Image: CBA (left-right reversed)
Water Image: Top-bottom flipped representation
3. Types of Mirror and Water Image Questions
Mirror Image Questions:
Object/figure is reflected in a vertical mirror.
Example: Original PQR → Mirror Image RQP
Water Image Questions:
Object/figure reflected in water placed below it.
Example: Original UP → Water Image PU
Combination Questions:
May involve mirror + rotation or water + rotation.
Alphabet and Number Images:
Often letters or numbers are used (A, H, M, 3, 8, 6).
Example: Letter B in mirror →
4. Previous Year SSC CGL Examples
2018 Tier I: Original: 324 → Mirror Image
Answer: 423
2019 Tier I: Original: Letter F → Mirror Image
Answer:
2020 Tier I: Original: MIRROR → Mirror Image
Answer: RORRIM
Practicing previous year questions improves speed in visualizing reflections and rotations.
5. Strategy to Approach Mirror and Water Image Questions
- Visualize carefully: Mentally or sketch the figure
- Remember flip rules: Mirror → Left ↔ Right, Water → Top ↔ Bottom
- Focus on symmetry: Letters like A, H, M, T remain the same in mirror
- Practice alphabets, numbers, and figures: Familiarity reduces errors
- Check orientation: Always verify if it's vertical or horizontal reflection
6. Quick Recap
- Mirror Image → left-right reversal
- Water Image → top-bottom reversal
- Some letters and numbers remain unchanged due to symmetry
- Practice improves accuracy and speed
7. Practice Questions
Try solving these to test your understanding:
1. Original: EAGLE → Mirror Image?
2. Original: 12 → Mirror Image?
3. Original: Letter S → Water Image?
4. Original: Number 69 → Mirror Image?
5. Original: Figure of a triangle pointing upwards → Water Image?
Click for Answers
1. ELGAE (Left-right reversal)
2. 21 (Left-right reversal)
3. S remains same (Symmetric in water image)
4. 69 (69 becomes 69 in mirror due to symmetry)
5. Triangle pointing downwards (Top-bottom reversal)
Solve these by mentally flipping or sketching the mirror/water images.
