Understanding the Letter Coding Pattern

The problem asks us to decipher a specific coding pattern used to transform the word "TEMPLE" into "ELPMET" and then apply the same pattern to code the word "CHURCH". These types of questions test your ability to recognize logical sequences and transformations between sets of letters or numbers.

Analyzing the TEMPLE to ELPMET Transformation

Let's look closely at the relationship between the letters in the original word "TEMPLE" and the coded word "ELPMET".

Original word: TEMPLE

Coded word: ELPMET

We can observe the positions of the letters:

Comparing the letters at corresponding positions doesn't immediately show a simple substitution like A becomes B. Let's try comparing the letters in the coded word to the letters in the original word based on their sequence:

• The first letter of the coded word is 'E', which is the last letter of TEMPLE.
• The second letter of the coded word is 'L', which is the fifth letter (second last) of TEMPLE.
• The third letter of the coded word is 'P', which is the fourth letter (third last) of TEMPLE.
• The fourth letter of the coded word is 'M', which is the third letter (fourth last) of TEMPLE.
• The fifth letter of the coded word is 'E', which is the second letter (fifth last) of TEMPLE.
• The sixth letter of the coded word is 'T', which is the first letter (sixth last) of TEMPLE.

This shows a clear pattern: the coded word is simply the reverse of the original word. The letters of TEMPLE are written in reverse order to get ELPMET.

Let's represent this reversal:

Reading TEMPLE from right to left gives E, L, P, M, E, T, which is ELPMET.

Applying the Reversal Pattern to CHURCH

Now, we apply the same reversal pattern to the word "CHURCH".

Original word: CHURCH

We need to write the letters of CHURCH in reverse order. The letters are C, H, U, R, C, H.

Reading CHURCH from right to left gives:

• Last letter: H
• Second last letter: C
• Third last letter: R
• Fourth last letter: U
• Fifth last letter: H
• Sixth letter: C

Putting these letters together in this order gives HCRUHC.

So, the coded word for CHURCH is HCRUHC.

Evaluating the Options

Let's compare our derived coded word (HCRUHC) with the given options:

1. HCURHC - Does not match HCRUHC.
2. HCRUHC - Matches HCRUHC.
3. HCURCH - Does not match HCRUHC.
4. HCRUCH - Does not match HCRUHC.

The coded word HCRUHC correctly follows the reversal pattern identified from the TEMPLE to ELPMET transformation.

Conclusion

The coding pattern used is the reversal of the original word. Applying this pattern to CHURCH results in HCRUHC.

Additional Information on Coding Patterns

Coding and decoding problems in reasoning often involve various patterns. Besides simple reversal, other common patterns include:

• Letter Shifting: Each letter is shifted a fixed number of positions forward or backward in the alphabet (e.g., A becomes C, B becomes D, etc.).
• Alphabet Position: Letters are replaced by their position in the alphabet (A=1, B=2, etc.).
• Substitution: Specific letters are replaced by other specific letters according to a rule (e.g., all vowels are replaced by the next vowel).
• Jumbling: Letters within a word are rearranged based on a specific rule (like the reversal we saw, or swapping first and last letters, etc.).
• Combination of Patterns: Sometimes, multiple patterns are applied together.

Identifying the pattern is the key to solving such problems. Always look for the simplest pattern first, such as reversal or simple shifting, before considering more complex rules.
