Alphabetical Pattern Analysis

The question presents a relationship between letter pairs based on their position in the English alphabet. We need to identify this pattern and apply it to find the related pair for NPRS.

Identifying the Coding Logic

Let's analyze the first pair: EGDH to FIFI.

• E is the 5th letter, F is the 6th letter. Difference: $6 - 5 = +1$.
• G is the 7th letter, I is the 9th letter. Difference: $9 - 7 = +2$.
• D is the 4th letter, F is the 6th letter. Difference: $6 - 4 = +2$.
• H is the 8th letter, I is the 9th letter. Difference: $9 - 8 = +1$.

The pattern observed is +1, +2, +2, +1 for the positions of the letters.

Verifying the Pattern

Let's verify this pattern with the second pair: JMHL to KOJM.

• J (10th) + 1 = K (11th)
• M (13th) + 2 = O (15th)
• H (8th) + 2 = J (10th)
• L (12th) + 1 = M (13th)

The pattern (+1, +2, +2, +1) holds true for the second pair as well.

Applying the Pattern to NPRS

Now, we apply the same +1, +2, +2, +1 pattern to NPRS:

• N is the 14th letter. $14 + 1 = 15$. The 15th letter is O.
• P is the 16th letter. $16 + 2 = 18$. The 18th letter is R.
• R is the 18th letter. $18 + 2 = 20$. The 20th letter is T.
• S is the 19th letter. $19 + 1 = 20$. The 20th letter is T.

Therefore, NPRS is related to ORTT.
