Given the following
Input : I am talking about your Delhi Patna Agra.
What step will be the following arrangement ?
About am I talking Delhi Agra Patna you.

Considering the block of logic, and substituting words by their position in the statement, i.e Original statement (You do things to help others in difficulty) -> 12345678

Step 1: 21645387

Step 2: 26154837

Step 3: 26518437

Step 4: 62581473

...

Consider the statement given in the question, I am talking about your Delhi Patna Agra.

Assigning index to each word in their order in the statement:

I - 1

am - 2

talking - 3  

about - 4 

your - 5

Delhi - 6

Patna - 7

Agra - 8

The second statement is About am I talking Delhi Agra Patna you. Writing in the form of indices of the words in the original statement, it becomes 42136875.

Step 8 arrangement gives us the same.

For getting step 8: We impose step 4 transformation on the step-4 transformed word 62581473.

Let's suppose the Step-4 transformed word is A, an the Step-8 transformed word is B.

Therefore applying Step-4 transformation on A will give us B.

A = 62581473

B = 62581473 transformation on A = [6 index of A][2 INDEX OF A][5 index of A][8 index OF A][1 index of A][4 index of A][7 index of A][2 index of A] = 42136875.

Hence the right answer is step VIII.
