In a certain code the letter group GIK is related to PRT. Using the same alphabetical pattern, to which group of letters will DFH be related?

Difficulty: Medium

Correct Answer: MOQ

Explanation:


Introduction / Context:
This is a three letter to three letter code analogy. The first group GIK is converted to PRT by an apparent uniform shift in the alphabet. The same transformation must then be applied to DFH in order to find the correct coded group in the answer choices.


Given Data / Assumptions:

  • Original letters: GIK
  • Coded letters: PRT
  • Target original letters: DFH
  • All coding uses forward shifts within the English alphabet without reversing order.


Concept / Approach:
To solve such questions, you should convert each letter to its numerical position and then find the difference between corresponding letters. If the same amount is added to each letter, that constant shift becomes the coding rule, which can be applied to any new letter group to find its code.


Step-by-Step Solution:

Step 1: Write positions for GIK. G is 7, I is 9, K is 11. Step 2: Write positions for PRT. P is 16, R is 18, T is 20. Step 3: Compute shifts. From G (7) to P (16) is +9. From I (9) to R (18) is +9. From K (11) to T (20) is +9. So the rule is plus nine for each letter. Step 4: Now find positions for DFH. D is 4, F is 6, H is 8. Step 5: Add 9 to each: 4 + 9 = 13 (M), 6 + 9 = 15 (O), and 8 + 9 = 17 (Q). So DFH becomes MOQ.


Verification / Alternative check:
Confirm that MOQ is present among the options and check that no other option corresponds to a constant shift of +9 from DFH. Rechecking the shift from GIK to PRT ensures there was no miscalculation. Since the same +9 rule works perfectly for both triplets, MOQ is the unique correct code.


Why Other Options Are Wrong:

  • LNP does not match a consistent shift of +9 from DFH; the underlying letter positions do not align.
  • RPN would require different shifts for different letters and breaks the uniform rule.
  • JLN arises from a smaller shift and does not reflect the needed +9 step.
  • NQS also does not correspond to simply adding 9 to each of D, F, and H.


Common Pitfalls:
Some learners check only the first letter pair and choose any option where D appears to move close to M or N without confirming the remaining letters. Alphabet coding questions require consistent application of the rule across all positions. Always verify every letter and do not rely on partial matches or visual guesses.


Final Answer:
Using the same alphabetical pattern, DFH is coded as MOQ.
