Directions : Read the following information carefully and answer the following questions.
A number arrangement machine when given an input line of numbers 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 following 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?

  1. A.

    uragedz turvivf

  2. B.

    eangerout dannou

  3. C.

    euplicatf eangerout

  4. D.

    turvivf , euplicatf

  5. E.

    None of these

Show answer & explanation

Correct answer: D

Concept: This is an input-rearrangement (input-output) machine. Each step applies one fixed rule to the output of the previous step, so to reach any step you must first reproduce every earlier step in order. Identify each rule from the worked illustration, then replay the same rules on the new input.

Rules derived from the illustration:

  1. Step I rule — arrange the words in descending dictionary (alphabetical) order, comparing letter by letter from the first letter; words sharing a starting letter are ordered by the next differing letter (so duplicate precedes dangerous).

  2. Step II rule — inside each word, advance the first letter and the last letter by one position in the alphabet (+1); every middle letter stays unchanged. Check: stadium becomes ttadiun (s to t, m to n).

  3. Step III rule — write the letters of each word in alphabetical order.

  4. Step IV rule — advance every letter of each word by one position (+1).

  5. Step V rule — arrange the whole line in ascending alphabetical order. The order of words within a line stays fixed from Step I through Step IV; only Step I and Step V re-order the line.

Applying to the input dangerous duplicate murder cannot survive triangle:

  1. Step I (descending dictionary order): triangle, survive, murder, duplicate, dangerous, cannot.

  2. Step II (first +1, last +1 on each word): triangle to urianglf, survive to turvivf, murder to nurdes, duplicate to euplicatf, dangerous to eangerout, cannot to dannou.

So Step II reads: urianglf turvivf nurdes euplicatf eangerout dannou.

Locating nurdes: nurdes is the Step II form of murder. The word standing immediately to its left is turvivf and the word immediately to its right is euplicatf.

Cross-check: reverse Step II on the neighbours — turvivf gives survive (t to s, f to e) and euplicatf gives duplicate (e to d, f to e) — and survive, murder, duplicate are consecutive in the Step I descending order, which confirms the pair.

Answer: turvivf , euplicatf.
