What is the sum of the numbers which are 2nd from the left end in step IV and 3rd from the right end in step II?

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.
Input: 23 Services 48 and 91 under Banking 37 maintenance 18
Step I:and 23 Services 48 under Banking 37 maintenance 18 91
Step II:and Banking 23 Services under 37 maintenance 18 91 48
Step III:and Banking maintenance 23 Services under 18 91 48 37
Step IV:and Banking maintenance Services under 18 91 48 37 23
Step V:and Banking maintenance Services under91 48 37 23 18
And step V is the last step of this arrangement.
As per the rules followed in the above steps, find out in each of the following questions the appropriate step for the given input.
Input: 36 Official 73 hour 22 on parliament 25 changed 46

The correct answer is 98.

To find the solution, we first need to understand the logic of the rearrangement machine from the given illustration.

Let's analyze the illustration:
Input: 23 Services 48 and 91 under Banking 37 maintenance 18
Step I: and 23 Services 48 under Banking 37 maintenance 18 91
Step II: and Banking 23 Services under 37 maintenance 18 91 48
Step III: and Banking maintenance 23 Services under 18 91 48 37
Step IV: and Banking maintenance Services under 18 91 48 37 23
Step V: and Banking maintenance Services under 91 48 37 23 18

Rules followed by the machine:
1. In each step, one word is shifted to the left side (in alphabetical order: "and", "Banking", "maintenance", "Services", "under").
2. In each step, one number is shifted to the right side (in descending order: 91, 48, 37, 23, 18).
3. In each step, the newly arranged word is placed at the leftmost available position of the word block, and the newly arranged number is placed at the rightmost available position of the number block.

Now, let's apply these rules to the given input:
Input: 36 Official 73 hour 22 on parliament 25 changed 46

Let's identify the words and numbers:
Words in alphabetical order: changed, hour, Official, on, parliament
Numbers in descending order: 73, 46, 36, 25, 22

Let's trace the steps for our input:
Input: 36 Official 73 hour 22 on parliament 25 changed 46

Step I:
We arrange the first word alphabetically ("changed") on the left, and the largest number ("73") on the right.
Step I: changed 36 Official hour 22 on parliament 25 46 73

Step II:
We arrange the next word ("hour") on the left after "changed", and the next largest number ("46") on the right, inside/before "73".
Step II: changed hour 36 Official 22 on parliament 25 73 46

Step III:
We arrange the next word ("Official") on the left, and the next largest number ("36") on the right.
Step III: changed hour Official 22 on parliament 25 73 46 36

Step IV:
We arrange the next word ("on") on the left, and the next largest number ("25") on the right.
Step IV: changed hour Official on 22 parliament 73 46 36 25

Now we identify the required elements:
1. The number which is 2nd from the left end in Step IV:
Looking at Step IV: "changed hour Official on 22 parliament 73 46 36 25"
The elements from the left are:
1st: changed
2nd: hour (Note: The question asks for the sum of the "numbers" which are at these positions. Let's look at the elements. Wait, is "hour" a number? No, the question says "sum of the numbers which are 2nd from the left end in step IV and 3rd from the right end in step II". In Indian competitive exams, the phrasing "numbers which are [position]" usually refers to the actual numbers that occupy those positions if we only count the numbers, or it refers to the element at that position assuming it is a number, or it is a translation error for "elements". Let's check both possibilities.)

Let's check the elements at the specified positions:
In Step IV: changed hour Official on 22 parliament 73 46 36 25
If we look at the positions of the numbers only, or if we look at the overall elements:
Let's list all elements of Step IV: [changed, hour, Official, on, 22, parliament, 73, 46, 36, 25]
Wait! Let's count elements from the left in Step IV:
1st from left: changed
2nd from left: hour (word)
Let's look at numbers from the left in Step IV:
Numbers are: 22, 73, 46, 36, 25
1st number from left: 22
2nd number from left: 73
Let's check Step II: changed hour 36 Official 22 on parliament 25 73 46
Elements from the right in Step II:
1st from right: 46
2nd from right: 73
3rd from right: 25
Let's check if we sum the numbers:
If 2nd number from left in step IV is 73, and 3rd from right in step II is 25:
Sum = $73+25=98$.
This perfectly matches our correct option 98.

Let's verify the calculations:
2nd number from the left in step IV = 73
3rd number from the right in step II = 25
Sum = $73+25=98$.
