Answers:

Q.(1- 5): In the first step, the word that comes first in the reverse alphabetical order comes to the first place and the rest of the line shifts rightward. In the next step, the largest number occupies the next place and the rest of the line shifts rightward. This goes on alternately till the words get arranged in

the reverse alphabetical order and the numbers in a descending order.

1-2;

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

Hence 7 − 3 = 4 more steps will be required.

2-3;

Input : any how 49 24 far wide 34 69

Step I: wide any how 49 24 far 34 69

Step II: wide 69 any how 49 24 far 34

Step III: wide 69 how any 49 24 far 34

Step IV: wide 69 how 49 any 24 far 34

Step V: wide 69 how 49 far any 24 34

Step VI: wide 69 how 49 far 34 any 24

Hence, Step V will be the last but one.

3-4; We can't proceed backward.

4-4;

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.

Since the line is already arranged, there will be no 4th step.

Step II: war 58 box cart 33 49 star 24

Step III: war 58 star box cart 33 49 24

Step IV: war 58 star 49 box cart 33 24
