When a number arrangment machine is given an input line of numbers, it arranges them following is a particular rule. The following is an illustration of an input and its rearrangement.
`{:("Input: 33 91 79 23 29 60 12 35"),("Step I: 99 273 69 77 120 24 105"),("Step II: 174 36 168 8 43 121 81"),("Step III: 28 18 48 8 12 2 8"),("Step IV: 14 9 24 4 6 1 4"):}`
Step IV, is the last step of the above arragement as the intended arrangement is obtained. As per the rules followed in the given steps find out appropriate steps for the given input
Input : `" 39 36 47 52 68 71 91 77"`
Which element is `4^(th)` to the right of the one which is `3^(rd)` to the left element in step III ?

Options

A. (A) 8
B. (B) 6
C. (C) 21
D. (D) 192

Answer

A

Explanation

In this input output question only numbers is arranged in each step. Let us understand the logic behind it-in each step the numbers are arranged
In step 1: all the even number (input) are multiplied with 2 and all the odd numbers are multiplied with 3.
Step 2: is given in the pattern as firstly the numbers are subtracted and then added respectively.
Step 3: the resultant of the multiplication of its digits in the previous step
Step 4: The numbers in the previous step is divided by 2
