INPUT-OUTPUT
 Directions: Study the following information carefully and answer the given questions:
 A word and number arrangement machine when given an input line of words and numbers rearranges them following a particular rule in each step. The following is an illustration of input and rearrangement. (All the numbers are two-digit numbers.)
 Input:   tall     48   13   rise   alt   99   76   32  wise   jar   high   28   56   barn
 Step I: 13   tal1   48   rise   99   76   32  wise  jar   high   28   56   barn   alt
 Step II:    28   13   tall   48   rise   99   76   32   wise   jar   high   56   alt   bam
 Step III:  32   28   13   tall   48   rise   99   76  wise   jar   56   alt   barn   high
 Step IV: 48  32   28   13   tall   rise   99   76   wise 56   alt   barn   high   jar
 Step V:  56   48   32   28   13   tall   99   76   wise  alt  barn  high   jar   rise
 Step VI: 76   56   48   32   28   13   99   wise  alt   barn   high   jar   rise   tall
 Step VII: 99   76   56   48   32   28   13   alt   barn  high  jar  rise  tall   wise
 And Step VII is the last step of the above input, as the desired arrangement is obtained.
 As per the rules followed in the above steps, find out in each of the following questions the appropriate step for the given input.
 Analysis: On observing the last step it is observed that numbers are arranged in the descending order from left end and the words are arranged in the alphabetical order after the numbers from the left end. The first six steps reveal that one number and one word are arranged in the respective order in each step. Each time the remaining number/ numbers are pushed to the right. The smallest number comes to the left end and the word which comes first in the alphabetical order goes to the right end. The next number adds to the left end and the next word adds to the right end.
 Questions:
 Input: 84   why   sit   14   32   not   best   ink   feet   51   27   vain   68   92 (All the numbers are two-digit numbers.)
 1.    Which step number is the following output?
     32 27 14 84 why sit not 51 vain 92 68 feet best ink
 1) Step V        2) Step VI
 3) Step IV        4) Step III
 5) There is no such step.
 A:    5.
     There will no such step. On observing the given output, the numbers 32, 27 and 14 are in descending order. This  indicates the III step of output. But in the III step the last three words will be 'best, feet, ink'. But in the given output the last three words are 'feet, best, ink'. For the given input, the given output can't be any step.
 2.    Which word/number would be at 5th position from the right in Step V?
     1) 1        2) 92    3) feet   
     4) best    5) why
 A:    4.
     In the V step, the first five numbers are arranged in descending order and five words are arranged in the reverse alphabetical order from the right end or alphabetical order from the left end. So the word in the 5th position from the right end will be 'best'.
 3.    How many elements (words or numbers) are there between 'feet' and '32' as they appear in the last step of the output?
     1) One       2) Three   3) Four               4) Five         5) Seven
 A:    2.
     The last step of output for the given input will be 92   84   68   51   32   27   14   best   feet   ink    not   sit   vain   why The elements between 'feet' and '32' are 27, 14 and best. So the number of elements is 3.
