Explanation

• The logic used in this coding system is to replace each letter with its corresponding position in the English alphabet (A=1, B=2, C=3, and so on).
• The word 'DARK' is coded by concatenating the positions of its letters: D(4), A(1), R(18), K(11) to form '411811'.
• Similarly, 'READ' is coded as R(18), E(5), A(1), D(4) to form '18514'.
• Based on this consistent pattern, the letter 'E' corresponds to its alphabetical position, which is 5.

Why Other Options Were Wrong

• Option B: The number 1 represents the letter 'A', not 'E'. As seen in the code for 'READ' (18514), 'A' is coded as 1.
• Option C: The number 8 represents the letter 'H'. It does not fit the established pattern for 'E'.
• Option D: The number 4 represents the letter 'D'. As seen in the code for 'DARK' (411811), 'D' is coded as 4.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning - Coding-Decoding as background academic context rather than a clinical decision trigger.
• This question tests logical reasoning, a key component of the general intelligence and aptitude sections of many nursing entrance and recruitment exams.
• While not a clinical skill, the ability to quickly identify patterns and solve problems is a valuable cognitive skill for nurses, who must often think critically and make logical decisions under pressure.
• What if the code for 'DARK' was '2326916'? This would suggest a reverse alphabetical order (A=26, Z=1), where D=23, A=26, R=9, K=16. The logic would shift from forward to reverse positioning, and the code for 'E' would become 22.

How to Approach the Question

• First, analyze the given examples: 'DARK' is coded as '411811' and 'READ' is coded as '18514'.
• Write down the letters of the first word ('D', 'A', 'R', 'K') and try to find a numerical relationship. A common starting point is their standard alphabetical positions.
• Assign the positional values: D=4, A=1, R=18, K=11.
• Compare this sequence of numbers with the given code. Observe that concatenating the positional values (4, 1, 18, 11) exactly forms the code '411811'.
• Verify this logic with the second example, 'READ'. The positions are R=18, E=5, A=1, D=4. Concatenating these gives '18514', which matches the provided code.
• Since the pattern is confirmed, apply it to find the code for 'E'. The alphabetical position of 'E' is 5.
