Directions : Read the following information carefully and answer the following questions.
A number arrangement machine when given an input line of words rearranges them following a particular rule. The following is an illustration of input and rearrangements.
Input: stadium language lunatic ambition condition consonant
Step I: stadium lunatic language consonant condition ambition
Step II: ttadiun munatid manguagf donsonanu donditioo bmbitioo
Step III: adinttu adimntu aafggmnu adnnnoosu ddiinooot bbiimoot
Step IV: bejouuv bejnouv bbghhnov beooopptv eejjopppu ccjjnppu
Step V: bbghhnov bejnouv bejouuv beooopptv ccjjnppu eejjopppu
Step V is the last step of the rearrangements. Based on the above logic, rearrange the given input.
Input: dangerous duplicate murder cannot survive triangle
Which words are immediate left and immediate right of ‘nurdes’ in Step II respectively?
- A.
uragedz turvivf
- B.
eangerout dannou
- C.
euplicatf eangerout
- D.
turvivf , euplicatf
- E.
None of these

Show answer & explanation
Correct answer: D
Concept
This is an input-output “word arrangement machine”: each step applies one fixed transformation to the line of words from the previous step, and the same five rules repeat for any new input. Decode every rule from the illustration first, then replay them on the new line. The five rules here are:
Step I – reorder words: arrange all words in reverse (descending) alphabetical order.
Step II – shift ends: in each word, move the first letter and the last letter one place forward in the alphabet (a→b, …, z→a); inner letters stay.
Step III – sort letters: rearrange the letters of each word into ascending alphabetical order.
Step IV – shift all: move every letter of each word one place forward in the alphabet.
Step V – reorder words: arrange the resulting words in ascending alphabetical order.
Application to this input
New input: dangerous duplicate murder cannot survive triangle. The question only needs Step II, which is built on Step I, so work those two steps:
Step I (reverse alphabetical order): triangle, survive, murder, duplicate, dangerous, cannot.
Step II (first letter +1, last letter +1 on each Step-I word):
Step-I word | First +1 | Last +1 | Step-II word |
|---|---|---|---|
triangle | t → u | e → f | urianglf |
survive | s → t | e → f | turvivf |
murder | m → n | r → s | nurdes |
duplicate | d → e | e → f | euplicatf |
dangerous | d → e | s → t | eangerout |
cannot | c → d | t → u | dannou |
So Step II is: urianglf turvivf nurdes euplicatf eangerout dannou.
The target word ‘nurdes’ comes from ‘murder’. Its immediate neighbours in Step II are turvivf on the left (from ‘survive’) and euplicatf on the right (from ‘duplicate’).
Cross-check
Re-verify against the illustration’s Step II, where each word’s first and last letters were also bumped by one: stadium→ttadiun, ambition→bmbitioo – exactly the rule used here. The neighbours of ‘nurdes’ are therefore turvivf and euplicatf, in that order.
