If in a particular code noida is written as 39658, then how India will be written in the same code?

Appeared in: NCL (MP) Nursing Officer - 2019

Explanation

The problem uses a direct substitution cipher where each letter is consistently replaced by a specific digit.
From the word 'noida' being coded as '39658', we can deduce the following mapping: n=3, o=9, i=6, d=5, and a=8.
Using this established code, we can find the code for 'India'.
The letter 'I' is coded as 6, 'n' as 3, 'd' as 5, 'i' as 6, and 'a' as 8.
Assembling these digits in order gives the final code for 'India' as 63568.

Option A: This option incorrectly starts with '3', which is the code for 'n', not 'I'. The code for 'I' is '6'.
Option C: This option has an incorrect last digit. The code for 'a' is '8', not '9'. The digit '9' corresponds to the letter 'o'.
Option D: This option incorrectly swaps the codes for 'n' and 'd'. The code for 'n' is '3' and for 'd' is '5', so the sequence should be '35', not '53'.

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 the skill of coding and decoding through direct letter-to-number substitution as background academic context rather than a clinical decision trigger.
This type of question is not directly related to clinical nursing practice but is common in competitive exams to assess a candidate's logical reasoning and problem-solving abilities.
Strong analytical skills are crucial for nurses in various situations, such as interpreting patient data, troubleshooting equipment, and making quick, logical decisions under pressure.
What if the question used a different pattern, like reverse order or alphabetical position? The approach would change. One would need to first identify the new rule (e.g., a=1, b=2, etc., or a=26, b=25, etc.) before applying it to the target word.

How to Approach the Question

First, carefully examine the given word ('noida') and its corresponding code ('39658').
Determine the relationship between the letters and the numbers. Notice that it's a one-to-one mapping.
Create a key by listing each letter and its assigned number: n?3, o?9, i?6, d?5, a?8.
Take the new word ('India') that needs to be coded.
Substitute each letter of 'India' with its corresponding number from the key you created.
Combine the numbers in the correct sequence to form the final code.
