Introduction to Mirror Image

Mirror Image problems involve letter sequences where each letter is transformed to its mirror counterpart (A↔Z, B↔Y, C↔X, etc.). These problems test your understanding of alphabetical symmetry and the ability to apply the Atbash cipher transformation.

Prerequisites

Alphabet position knowledge Mirror formula: mirror position = 27 - original position Understanding of symmetrical pairs Memory of mirror pairs (A↔Z, B↔Y, etc.)
Why This Matters: Mirror Image problems appear in 1-2 questions in SSC CGL and Banking PO exams. They test understanding of alphabet symmetry and mirror transformations.

How to Solve Mirror Image Problems

1

Step 1: Convert the given letter to its position (A=1 to Z=26)

2

Step 2: Apply the mirror formula: mirror position = 27 - original position

3

Step 3: Convert the mirror position back to a letter

4

Step 4: For series, apply mirror transformation to each letter or find pattern in mirrored letters

5

Step 5: Mirror transformation is its own inverse (applying twice returns original)

6

Step 6: Verify the pattern holds for all given terms

Pro Strategy: Memorize the mirror pairs: A↔Z, B↔Y, C↔X, D↔W, E↔V, F↔U, G↔T, H↔S, I↔R, J↔Q, K↔P, L↔O, M↔N. The mirror transformation is an involution (applying it twice returns the original letter).

Example Problem

Example: If A↔Z, B↔Y, etc., find the mirror of 'C'. Solution: Step 1: C = position 3 Step 2: Mirror position = 27 - 3 = 24 Step 3: Position 24 = X Answer: X

Pro Tips & Tricks

  • A↔Z, B↔Y, C↔X, D↔W, E↔V, F↔U, G↔T, H↔S, I↔R, J↔Q, K↔P, L↔O, M↔N
  • Mirror position = 27 - original position
  • The middle pair is M(13) ↔ N(14)
  • Vowels map to consonants: A→Z, E→V, I→R, O→L, U→F
  • Mirror image is also called Atbash cipher
  • The mirror of a mirror is the original letter

Shortcut Methods to Solve Faster

Mirror of A = Z, Mirror of Z = A
Mirror of B = Y, Mirror of Y = B
Mirror of M = N, Mirror of N = M
Sum of mirror pair positions = 27
To find mirror quickly, count from opposite end

Common Mistakes to Avoid

Using 26 - position instead of 27 - position (off by one error)
Confusing mirror image with reverse order of letters
Forgetting that mirror applies to each letter individually
Not maintaining letter order after transformation
