Introduction to Two-Letter Combination

Prerequisites

Single letter water images Understanding of order reversal in water images String reversal concept

Why This Matters: Two-Letter Combination problems appear in 1-2 questions in SSC CGL and Banking exams. They test sequential water image reasoning.

How to Solve Two-Letter Combination Problems

Step 1: Write the given two-letter combination

Step 2: Reverse the order of the letters (first becomes last, last becomes first)

Step 3: For each letter in the reversed string, find its water image

Step 4: Apply letter water image rules (A,H,I,O,T,U,V,X,Y remain same; M↔W)

Step 5: Combine the transformed letters in order

Step 6: This combined string is the water image

Pro Strategy: Remember that water image requires both reversal of order and individual character transformation. Always reverse first, then transform each character.

Example Problem

Example: Find the water image of 'MW'. Solution: Step 1: Given string: M W Step 2: Reverse order: W M Step 3: Water image of W = M Step 4: Water image of M = W Step 5: Combine: M W Step 6: Water image of 'MW' is 'MW' Answer: MW

Pro Tips & Tricks

Always reverse the string order first
Then apply individual character water image rules
For symmetrical letters, transformation is simple (same letter)
M and W swap places in water image
The water image of 'XY' is 'YX' if X and Y are symmetrical letters
Practice with different letter combinations

Shortcut Methods to Solve Faster

Water image of string = reverse(string) with each character transformed

For symmetrical letters: water image = reverse(string)

For M/W pairs: water image = swap M↔W and reverse

If all letters are symmetrical, water image = reverse(string)

Common Mistakes to Avoid

Forgetting to reverse the order of letters

Transforming letters before reversing (order matters)

Applying transformation to original order only

Not handling M↔W transformation correctly
