Conditional Rules
Conditional Rules problems apply different coding rules based on letter properties (vowel/consonant, position parity, etc.). For example, vowels might be replaced by numbers while consonants are shifted. These problems test your ability to apply rule-based transformations.

Prerequisites
How to Solve Conditional Rules Problems
Step 1: Identify the rule for vowels and the rule for consonants
Step 2: Check each letter of the word to determine if it is a vowel or consonant
Step 3: Apply the vowel rule to vowel letters
Step 4: Apply the consonant rule to consonant letters
Step 5: Combine the transformed letters in the same order
Step 6: Verify the transformation is consistent with given examples
Step 7: Present the coded word
Example Problem
Example: Vowels are replaced by their position number (A=1,E=2,I=3,O=4,U=5). Consonants are shifted by +1 (B→C, C→D). Code 'CAT'. Solution: Step 1: C is consonant → +1 shift → D Step 2: A is vowel → position number → 1 Step 3: T is consonant → +1 shift → U Step 4: Coded word = D1U Answer: D1U
Pro Tips & Tricks
- Vowels: A, E, I, O, U (sometimes Y is considered a vowel, check problem statement)
- Common vowel rules: replace with number (A=1,E=2,I=3,O=4,U=5), shift by +1 (A→B, E→F), replace with next vowel (A→E, E→I)
- Common consonant rules: shift by +1, shift by -1, replace with opposite letter, remain unchanged
- Write the word and mark vowels vs consonants before coding
- Y is usually treated as a consonant unless specified otherwise
- Some problems use 'if position is odd/even' instead of vowel/consonant
