Solution:
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 illustrator of input and rearrangement.
Input : but 32 71 glory fair south 65 84
Step I : south but 32 71 glory fair 65 84
Step II : south 84 but 32 71 glory fair 65
Step III : south 84 glory but 32 71 fair 65
Step IV : south 84 glory 71 but 32 fair 65
Step V : south 84 glory 71 fair but 32 65
Step VI : south 84 glory 71 fair 65 but 32
and Step VI is the last step of the rearrangement.
As per the rules followed in the above steps, find out in each of the following questions the appropriate step for the given input.
Q.2)
Step III of an input is : year 92 ultra 15 23 strive house 39
How many more steps will be required to complete the rearrangement ?
1) 3
2) 4
3) 2
4) 5
5) None Of these
Correct Ans:
2
Solution:
Due to study carefully in various steps in the given input, this implies that in every step a word or a number arranged. In first step a word and in second step a number is arrange. Words are arrange according to the alphabetical order while numbers are arrange in descending order.
Step III: year 92 ultra 15 23 strive house 39
Step IV:year 92 ultra 39 15 23 strive house.
Step V: year 92 ultra 39 strive 15 23 house.
Step VI: : year 92 ultra 39 strive 23 15 house.
Step VII: year 92 ultra 39 strive 23 house 15.
In the same way IV steps will be required to complete the rearrangement.
Q.3)

Which of the following steps will be the last but one ?
1) VI
2) VII
3) V
4) VIII
5) None Of these
Correct Ans:
3
Solution:
Due to study carefully in various steps in the given input, this implies that in every step a word or a number arranged. In first step a word and in second step a number is arrange. Words are arrange according to the alphabetical order while numbers are arrange in descending order. Step II of an input is: town 74 pair 15 31 nice job 42 Which of the following is definitely the input ? Due to study carefully in various steps in the given input, this implies that in every step a word or a number arranged. In first step a word and in second step a number is arrange. Words are arrange according to the alphabetical order while numbers are arrange in descending order. Input : play over 49 37 12 match now 81 Which of the following will be step IV ? Due to study carefully in various steps in the given input, this implies that in every step a word or a number arranged. In first step a word and in second step a number is arrange. Words are arrange according to the alphabetical order while numbers are arrange in descending order.
Input : any how 49 24 for wide 34 69.
Step I: wide any how 49 24 for 34 69.
Step II: wide 69 any how 49 24 for 34.
Step III: wide 69 how any 49 24 for 34.
Step IV: wide 69 how 49 any 24 for 34.
Step V: wide 69 how 49 for any 24 34.
StepVI :wide 69 how 49 for 34 any 24.
Second last step is V.
Q.4)
1) pair 15 31 town nice job 42 74
2) pair 15 town 31 74 nice job 42
3) pair 15 town 74 31 nice job 42
4) Cannot be determined
5) None Of these
Correct Ans:
4
Solution:
Step II : town 74 pair 15 31 nice job 42.
Hence we cannot get input from the given step.
Q.5)
1) play 81 over 49 37 match now
2) play 81 over 49 37 match now
3) play 81 over 49 now 37 match 12
4) There will be no such step
5) None Of these
Correct Ans:
4
Solution:
Input %play over 49 37 12 match now 81.
Step I : play 81 over 49 37 12 match now.
Step II : play 81 over 49 now 37 12 match.
Step III : play 81 over 49 now 37 match 12.
This input only 2 step Hence 4th step is not possible.
