Types of Mirror Images Questions
Competitive exams test Mirror Images through various question formats. Below are the main types with solved examples and practice questions:
This type involves finding the mirror image of given alphabets or words. Key points to remember:
- Some letters appear identical in mirror (A, H, I, M, O, T, U, V, W, X, Y)
- Letters like B, C, D, E, F, G, J, K, L, N, P, Q, R, S, Z change in mirror
- The mirror image reverses left and right but not top and bottom
Solved Example 1:
What will be the mirror image of the word "REASONING"?
Solution:
- 1. Write the word normally: REASONING
- 2. Identify each letter's mirror image:
- R → Mirrored R (right leg becomes left)
- E → Mirrored E (horizontal lines reverse)
- A → A (symmetrical)
- S → Mirrored S (direction reverses)
- O → O (symmetrical)
- N → Mirrored N (slant reverses)
- I → I (symmetrical)
- N → Mirrored N (slant reverses)
- G → Mirrored G (open side reverses)
- 3. The complete mirror image will appear as: GNINOSAƎЯ (Note: Some characters may not display perfectly due to font limitations)
- 4. In exams, you'll typically select from options rather than draw
Solved Example 2:
If the mirror is placed to the right of the word "MIRROR", what will be the correct mirror image?
Solution:
- 1. Original word: M I R R O R
- 2. With mirror on right, the image will appear to the right of the original
- 3. Analyze each letter:
- M → M (symmetrical)
- I → I (symmetrical)
- R → Mirrored R
- R → Mirrored R
- O → O (symmetrical)
- R → Mirrored R
- 4. The correct sequence will be: M I R R O R | Я Я O Я Я I M
- 5. In options, look for this pattern where symmetrical letters remain same
Solution:
When mirror is placed below:
- The image appears upside down below the original
- Letters that are vertically symmetrical (A, H, I, M, O, T, U, V, W, X, Y) remain same
- Other letters get inverted vertically:
- B → Inverted B (top and bottom reverse)
- A → A (symmetrical)
- N → Inverted N (slant reverses)
- K → Inverted K (diagonals reverse)
- I → I (symmetrical)
- N → Inverted N (slant reverses)
- G → Inverted G (open side reverses)
- The correct mirror image would be the word upside down with appropriate letter changes
- Note: Some letters like 'K' and 'G' change significantly when inverted
This type involves finding mirror images of numbers or numerical combinations. Important points:
- Some numbers appear identical in mirror (0, 1, 8)
- Numbers 2, 3, 4, 5, 6, 7, 9 change in mirror
- Multi-digit numbers reverse their order in mirror images
Solved Example 1:
What will be the mirror image of the number "2025"?
Solution:
- 1. Original number: 2 0 2 5
- 2. Analyze each digit:
- 2 → Mirrored 2 (looks different)
- 0 → 0 (symmetrical)
- 2 → Mirrored 2
- 5 → Mirrored 5 (looks different)
- 3. The complete mirror image will be the reversed sequence with each digit mirrored: 5↊ 2 0 2↊
- 4. Note: The exact appearance depends on font style, but the concept remains
Solution:
When mirror is placed to the left:
- The image appears to the left of the original
- Digits reverse their order and each digit is mirrored
- Original: 3 : 4 5
- Mirror image analysis:
- 3 → Mirrored 3
- : → : (symmetrical)
- 4 → Mirrored 4
- 5 → Mirrored 5
- The complete mirror image would be: 5↊ 4 : Ɛ
- Note: The colon remains unchanged as it's symmetrical
This type involves finding mirror images of geometric shapes or complex figures. Key aspects:
- Symmetrical shapes may appear identical in mirror
- Asymmetrical shapes will show clear left-right reversal
- Pay attention to internal patterns and markings
- Complex figures may combine multiple elements
Solved Example 1:
Consider a capital letter 'F' with a small circle in its top right corner. What will be its mirror image?
Solution:
- 1. Original figure: 'F' with circle in top right
- 2. The letter 'F' itself is asymmetrical and will reverse in mirror
- 3. The circle's position will change from top right to top left
- 4. The horizontal lines of 'F' will maintain their position but reverse direction
- 5. The correct mirror image will show a mirrored 'F' with circle in top left corner
Solution:
- Original: Right-pointing triangle with square on base
- Mirror image will reverse left and right:
- Triangle will point to the left
- Square will remain on base but shift to opposite side
- If original had square on right side of base, mirror will have it on left
- The vertical dimensions remain unchanged
- Internal angles of triangle remain same but orientation reverses
This special type involves determining actual time from a clock's mirror image or vice versa. Key formula:
Actual Time = 11:60 - Mirror Time
Solved Example 1:
If the mirror image of a clock shows 3:40, what is the actual time?
Solution:
- 1. Apply the formula: Actual Time = 11:60 - Mirror Time
- 2. Convert to minutes: 11×60 = 660 minutes
- 3. Mirror time 3:40 = 3×60 + 40 = 220 minutes
- 4. Subtract: 660 - 220 = 440 minutes
- 5. Convert back: 440 ÷ 60 = 7 hours and 20 minutes (7:20)
- 6. Verification: The mirror image of 7:20 should show 3:40 (as 11:60 - 7:20 = 3:40)
Solved Example 2:
What will be the mirror image of the time 2:30?
Solution:
- 1. Apply the same formula in reverse: Mirror Time = 11:60 - Actual Time
- 2. Convert to minutes: 11×60 = 660; 2:30 = 150 minutes
- 3. Subtract: 660 - 150 = 510 minutes
- 4. Convert back: 510 ÷ 60 = 8 hours and 30 minutes (8:30)
- 5. Verification: The mirror image of 8:30 should show 2:30 (as 11:60 - 8:30 = 2:30)
- 6. Alternative method: The hour hand at 8:30 points halfway between 8 and 9, which mirrors to halfway between 3 and 4 (2:30)
Solution:
- Apply formula: Actual Time = 11:60 - Mirror Time
- Convert mirror time to minutes: 4:15 = 255 minutes
- 11:60 = 660 minutes
- Subtract: 660 - 255 = 405 minutes
- Convert back: 405 ÷ 60 = 6 hours and 45 minutes (6:45)
- Verification: Mirror of 6:45 should show 4:15 (11:60 - 6:45 = 4:15)
- Note: The hour hand at 6:45 points 3/4 way from 6 to 7, which mirrors to 1/4 way from 4 to 5 (4:15)
Step-by-Step Solving Techniques
Visualization Before Drawing
Develop the skill to mentally visualize the mirror image before attempting to draw or select options:
- Hold an imaginary mirror on the specified side (left/right/top/bottom)
- Mentally flip the image across the mirror line
- Focus on key features that will change vs. remain same
- For text, visualize each character's mirrored form
- For shapes, identify symmetry lines and asymmetrical elements
- R → Mirrored R
- A → A (unchanged)
- H → H (unchanged)
- U → U (unchanged)
- L → Mirrored L
Symmetry Identification
Quickly identify symmetrical elements that won't change in mirror:
- For alphabets: A, H, I, M, O, T, U, V, W, X, Y remain same
- For numbers: 0, 1, 8 remain same
- For shapes: Identify lines of symmetry
- Mark symmetrical elements first to reduce work
- Focus only on asymmetrical elements that need transformation
Mirror image is same as original but reversed in order.
Clock Time Formula
For clock mirror problems, use the universal formula:
- Actual Time = 11:60 - Mirror Time
- Convert both times to minutes for calculation
- Subtract mirror time from 660 minutes (11×60)
- Convert result back to hours:minutes
- For times past 6:00, mirror time will be before 6:00
- 4:20 = 260 minutes
- 660 - 260 = 400 minutes
- 400 ÷ 60 = 6:40 actual time
Elimination Method
When options are given, eliminate incorrect choices systematically:
- First eliminate options with unchanged asymmetrical elements
- Then check order reversal for text/numbers
- Verify positions of specific features in shapes
- Compare with known symmetrical elements
- Select the option that satisfies all checks
Eliminate options where E or H change, or where order isn't reversed.
Pattern Memorization
Memorize common patterns to save time:
- Standard mirror forms of all alphabets and numbers
- Common word patterns (like city names, exam terms)
- Clock time relationships (e.g., 12:00 mirrors to 12:00)
- Geometric shape transformations
- Combination patterns (text + shapes)
- 3 mirrors to Ɛ-like shape
- 7 mirrors to ㄥ-like shape
- B mirrors to backward B
Feature Analysis
For complex figures, analyze individual features:
- Identify all components of the figure
- Determine which features are symmetrical
- Note positions of asymmetrical elements
- Track how each element transforms in mirror
- Reconstruct the image feature by feature
Mirror will show star on left with flag orientation reversed.
