Select the related letter from the given alternatives. ROLF : VTRM :: NODP : ?

Appeared in: Haryana CHO -2023

Explanation

The core logic involves a progressive alphabetical shift for each letter in the sequence.
The pattern established by ROLF to VTRM is an increasing addition of +4, +5, +6, and +7 to the alphabetical position of each letter, respectively.
Applying this same pattern to NODP: N (14) + 4 = R (18), O (15) + 5 = T (20), D (4) + 6 = J (10), and P (16) + 7 = W (23).
This calculation correctly yields the sequence RTJW.

Option B: This option does not follow the established +4, +5, +6, +7 pattern. For example, the first letter 'S' is N+5, not N+4.
Option C: This option is incorrect because the second letter is 'U'. The correct shift for the second letter 'O' (15) is +5, which results in 'T' (20), not 'U' (21).
Option D: This option applies a completely different and inconsistent set of shifts that do not match the +4, +5, +6, +7 sequence derived from the first pair.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain This question tests logical reasoning, specifically letter analogy based on a sequential mathematical pattern as background academic context rather than a clinical decision trigger.
This is a general intelligence question, not a clinical one. However, the analytical and pattern-recognition skills tested are crucial for nursing.
Nurses must recognize patterns in vital signs, lab results, and patient symptoms to identify improvement or deterioration.
For example, recognizing a pattern of gradually decreasing blood pressure and increasing heart rate is critical for identifying hypovolemic shock.

How to Approach the Question

First, identify the question as a letter analogy problem, where you need to find the relationship between the first pair of words to solve the second.
Assign numerical values to the letters of the first pair (ROLF and VTRM) based on their position in the alphabet (A=1, B=2, ...).
Calculate the difference between corresponding letters: R(18) to V(22) is +4, O(15) to T(20) is +5, L(12) to R(18) is +6, and F(6) to M(13) is +7.
Identify the consistent pattern, which is an increasing series of additions (+4, +5, +6, +7).
Apply this exact same pattern to the letters of the word 'NODP'.
Convert the resulting numbers back into letters to find the answer (18=R, 20=T, 10=J, 23=W), and select the matching option.
