Conditional Assertion
Conditional Assertion problems apply transformation rules that are conditional on properties of letters (vowel/consonant, position, etc.). For example, 'if vowel, replace with next letter; if consonant, replace with previous letter'. These problems test your ability to apply conditional logic to alphabet transformations.

Introduction to Conditional Assertion
Conditional Assertion problems apply transformation rules that are conditional on properties of letters (vowel/consonant, position, etc.). For example, 'if vowel, replace with next letter; if consonant, replace with previous letter'. These problems test your ability to apply conditional logic to alphabet transformations.
Prerequisites
How to Solve Conditional Assertion Problems
Step 1: Identify the condition(s) in the assertion
Step 2: Identify the transformation rule for each condition
Step 3: For each letter in the word, check which condition applies
Step 4: Apply the corresponding transformation to that letter
Step 5: Handle multiple conditions carefully (nested or sequential)
Step 6: Write the transformed word letter by letter
Step 7: Verify the transformation for each letter
Step 8: Present the final transformed word
Example Problem
Example 1: If a letter is a vowel, replace with next letter; if consonant, replace with previous letter. Apply to 'CAT'. Solution: Step 1: C is consonant → previous letter = B Step 2: A is vowel → next letter = B Step 3: T is consonant → previous letter = S Step 4: Result: B B S Answer: BBS Example 2: If letter position is odd, add 1; if even, subtract 1. Apply to 'BED'. Solution: Step 1: B=2 (even) → subtract 1 → 1=A Step 2: E=5 (odd) → add 1 → 6=F Step 3: D=4 (even) → subtract 1 → 3=C Step 4: Result: A F C Answer: AFC
Pro Tips & Tricks
- Identify vowels: A, E, I, O, U (sometimes Y)
- Consonants are all other letters
- Conditions can be based on: vowel/consonant, odd/even position, prime position, etc.
- Transformations can include: next letter, previous letter, mirror, skip, etc.
- For nested conditions, apply the innermost condition first
- Always check the condition for each letter individually
