Step 1: 131 fog angle post 75 lamp 31 iearn 58 outer 79 262
Step 2: angle 131 post 75 lamp 31 iearn 58 outer 79 262 fog
Step 3: 313 angle 131 post 75 lamp earn outer 79 262 fog 585
Step 4: earn 313 angle 131 post 75 outer 79 262 fog 585 lamp
Step 5: 757 earn 313 angle 131 post outer 262 fog 585 lamp 797
Step 5: outer 757 earn 313 angle 131 262 fog 585 lamp 797 post

This is the final arrangement and step 6 is the last step for this input.

Input: 28 hut under 75 out 45 12 break 21 pot 63 east

    Option C
    Explanation:
    Words: consonants and vowels taken in alternate steps. Vowel at first place, consonant at last.
    Numbers taken in ascending order – and added the first digit at the end while arrangement. like 13 -> 131, 26 -> 262, 31 ->313, 58 -> 585…..
    Now::
    Input: 28 hut under 75 out 45 12 break 21 pot 63 east
    Step 1: 121 28 hut under 75 out 45 break pot 63 east 212
    Step 2: east 121 28 hut under 75 out 45 pot 63 212 break
    Step 3: 282 east 121 hut under 75 out pot 63 212 break 454
    Step 4: out 282 east 121 under 75 pot 63 212 break 454 hut
    Step 5: 636 out 282 east 121 under pot 212 break 454 hut 757
    Step 6: under 636 out 282 east 121 212 break 454 hut 757 pot
  2. In step 6, if ‘out’ is related to ‘212’ in the same way as in step 2, ‘75’ is related to ‘63’ in a certain way, then in step 3, ‘under’ is related to which of the following in the same way?

Directions (6-10): Consider the following steps for given input and read the instructions to reach to the last step.

Instructions:
Step-I: Interchange the alphabets in input as arrows mentioned

Step-II: (i) If both letters are consonant and number is less than 5, then 1st consonant changes to next letter and 2nd consonant changes to previous letter in English alphabetical series.
(ii) If there is one vowel and one consonant, then consonant changes to next letter in English alphabetical series.
(iii) It there is single consonant, then add 2 to the number.
(iv) It there is single vowel, then vowel changes to previous letter in English alphabetical series.

Step-III: has been derived using a special pattern.

Input:

  1. What is the sum of all numbers in step II of given input?
    A) 42
    B) 40
    C) 33
    D) 36
    E) 38
    View Answer
     Option E
    Solution:

    Try to derive rules for step III, same as given for step II
    We see, 
    when there are both consonants like ST8, it changes to TS7, means when both consonants are there, (1st consonant + 1), (2nd consonant – 1) , and no changes (no – 1)
    Next, when there is single consonant like Z8, it changes to X8, so (consonant – 2)
    Next, when there is one vowel and one consonant, like NE1 -> NF4, given (vowel + 1) and (no +3)
    So rules for step III are:
    (i) If both letters are consonant, then 1st consonant changes to next letter, 2nd consonant changes to previous letter in English alphabetical series and subtract 2 from number.
    (ii) If there is one vowel and one consonant, then vowel changes to next letter and add 3 to the number.
    (iii) It there is single consonant, then consonant changes to next to next letter in English alphabetical series.
    (iv) If there are two vowels, then 2nd vowel changes to next letter and add 3 to the number.
    For given input:
         
  2. In last step, which of the following letter/s occur more than 2 times?
