Understanding Code Language and Decoding Patterns

This question requires us to decipher a specific code language based on two examples provided: 'BACKED' coded as 'GHNFDE' and 'CLOSER' coded as 'UHVROF'. We need to find the code for the word 'JUNIOR' using the same pattern.

Let's analyze the relationship between the original words and their coded forms. A common approach in such coding-decoding problems is to look for patterns related to letter positions in the alphabet (A=1, B=2, ..., Z=26) or simple shifts.

Let's write down the alphabetical position of each letter in the given words and their codes:

Let's calculate the sum of the positions for 'BACKED' and 'GHNFDE':

• Sum for BACKED: $2 + 1 + 3 + 11 + 5 + 4 = 26$
• Sum for GHNFDE: $7 + 8 + 14 + 6 + 4 + 5 = 44$

The difference in sums is $44 - 26 = 18$.

Now let's do the same for the second example, 'CLOSER' coded as 'UHVROF'.

Let's calculate the sum of the positions for 'CLOSER' and 'UHVROF':

• Sum for CLOSER: $3 + 12 + 15 + 19 + 5 + 18 = 72$
• Sum for UHVROF: $21 + 8 + 22 + 18 + 15 + 6 = 90$

The difference in sums is $90 - 72 = 18$.

The pattern observed is that the sum of the alphabetical positions of the letters in the coded word is 18 more than the sum of the alphabetical positions of the letters in the original word.

Applying the Pattern to JUNIOR

Now, let's apply this pattern to the word 'JUNIOR'. First, calculate the sum of the alphabetical positions for 'JUNIOR'.

Sum for JUNIOR: $10 + 21 + 14 + 9 + 15 + 18 = 87$.

Based on the identified pattern, the sum of the alphabetical positions of the letters in the coded word for 'JUNIOR' should be $87 + 18 = 105$.

Checking the Options

Let's calculate the sum of the alphabetical positions for each given option:

Comparing the sums of the options with the target sum (105), we find that option 4, 'URLQXM', has a sum of 105.

Therefore, based on the identified pattern, 'JUNIOR' is coded as 'URLQXM'.

Conclusion

The code language follows a pattern where the sum of the alphabetical positions of the letters in the coded word is consistently 18 greater than the sum of the alphabetical positions of the letters in the original word. By calculating the sum for 'JUNIOR' and adding 18, we determined the target sum for its code. Checking the options revealed that 'URLQXM' is the only word whose letters' positional sum matches this target.

Additional Information on Coding and Decoding

Coding and decoding questions are common in logical reasoning sections of various competitive exams. These questions test your ability to identify patterns and rules governing the transformation of words, numbers, or symbols.

Common types of coding-decoding patterns include:

• Letter Shifting: Each letter is shifted a fixed number of positions forward or backward in the alphabet.
• Reverse Letter Shifting: Letters are shifted a variable number of positions, often dependent on the letter's position in the word or its type (vowel/consonant).
• Alphabetical Position: The code uses the numerical position of letters in the alphabet.
• Reverse Alphabetical Position: Using position from Z=1, Y=2, etc.
• Opposite Letters: Using pairs of letters that are equidistant from the beginning and end of the alphabet (A-Z, B-Y, C-X, etc.).
• Jumbling or Rearrangement: The letters of the word are rearranged according to a specific rule or pattern.
• Word Substitution: Words are replaced by other words, symbols, or numbers based on a direct or indirect rule.
• Pattern based on Sum/Difference of Positions: As seen in this problem, the code might follow a rule based on the numerical sum or difference of letter positions.

To solve coding-decoding problems effectively, it's helpful to:

• Write down the alphabet and its positions (1-26).
• Write down opposite letter pairs.
• Compare the given words and their codes carefully to spot similarities or differences.
• Test different possible patterns systematically.
• Check the pattern with all given examples before applying it to the question word.
