Decoding Letter-Number Patterns in Coding Language

This question asks us to find the coded form of the word 'ACQUIRE' based on the patterns observed in the given examples: 'CONVERT' is coded as '34142221820', and 'FORTUNE' is coded as '6418205142'. We need to analyze these examples to figure out the coding rule.

Analyzing the Coding Pattern for CONVERT

Let's look at the word 'CONVERT' and its letters:

Observing the pattern, it appears that some letters are coded by their direct alphabetical position (C=3, N=14, V=22, R=18, T=20). However, the vowels O (position 15) and E (position 5) are coded differently (O=4, E=2).

Analyzing the Coding Pattern for FORTUNE

Let's look at the word 'FORTUNE' and its letters:

Again, consonants like F, R, T, and N are coded by their direct alphabetical position (F=6, R=18, T=20, N=14). The vowels O (position 15), U (position 21), and E (position 5) are coded as O=4, U=5, E=2.

Identifying the Coding Rule for Vowels and Consonants

Comparing the vowel codes to their positions in the sequence of vowels (A, E, I, O, U):

• A is the 1st vowel.
• E is the 2nd vowel.
• I is the 3rd vowel.
• O is the 4th vowel.
• U is the 5th vowel.

From the examples, we see:

• E is coded as 2 (which is its position in the vowel sequence).
• O is coded as 4 (which is its position in the vowel sequence).
• U is coded as 5 (which is its position in the vowel sequence).

This suggests the rule is:

• Consonants are coded by their alphabetical position (A=1, B=2, ..., Z=26).
• Vowels (A, E, I, O, U) are coded by their position in the vowel sequence (A=1, E=2, I=3, O=4, U=5).

Applying the Coding Rule to ACQUIRE

Now let's apply this rule to the word 'ACQUIRE'. First, identify each letter and whether it is a vowel or a consonant:

• A: Vowel (1st in sequence)
• C: Consonant (3rd letter)
• Q: Consonant (17th letter)
• U: Vowel (5th in sequence)
• I: Vowel (3rd in sequence)
• R: Consonant (18th letter)
• E: Vowel (2nd in sequence)

Now, let's find the code for each letter based on our rule:

Combining the codes for each letter of 'ACQUIRE' in order, we get: 1 3 17 5 3 18 2. When written together as a single string, this is 131753182.

Final Coded Form for ACQUIRE

Based on the derived coding rule, the word 'ACQUIRE' is coded as 131753182.

Additional Information on Coding and Decoding Questions

Coding-decoding questions test your ability to identify patterns and rules in a given set of examples and apply them to find a missing term. These patterns can involve:

• Letter shifting (e.g., A becomes B, B becomes C).
• Assigning numerical values based on alphabetical position (A=1, B=2, etc.).
• Assigning numerical values based on reversed alphabetical position (Z=1, Y=2, etc.).
• Applying different rules for vowels and consonants.
• Using reverse order of letters in the word.
• Combining multiple rules.

To solve such questions effectively, always:

• Write down the given words and their codes clearly.
• Write down the alphabetical positions of the letters.
• Try to find a relationship between the letters/positions and the codes.
• Look for different rules for vowels and consonants.
• Test your identified rule against all given examples.
• Apply the confirmed rule to the word you need to code or decode.

Understanding the difference between vowels (A, E, I, O, U) and consonants is often key in these types of problems, as they frequently have different coding rules.
