IBPS PO Reasoning: Seating and Arrangement / Word Arrangement questions with solutions

Q1. 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 the input and rearrangement. (All the numbers are two-digit numbers.) Input: monk 79 bill rock 34 73 hole 80 sand fog 22 jam 60 99 Step I: sand 99 monk 79 bill rock 34 73 hole 80 fog 22 jam 60 Step II: sand rock 99 80 monk 79 bill 34 73 hole fog 22 jam 60 Step III: sand rock monk 99 80 79 bill 34 73 hole fog 22 jam 60 Step IV: sand rock monk 99 80 79 jam 73 bill 34 hole fog 22 60 Step V: sand rock monk 99 80 79 jam hole 73 60 bill 34 fog 22 Step VI: sand rock monk 99 80 79 jam hole fog 73 60 34 bill 22 As per the rule followed in the above steps, find the appropriate step for the given input. Input: 23 mat belt 50 car 36 73 hay 66 owl 40 sell fool 47 Question: What is the difference between the sum of the first set of three numbers and the sum of the next set of three numbers in the last step?

1. 87
2. 66
3. 94
4. 38

Answer: 66

The arrangement follows a fixed alternating placement rule based on the sample. After applying the same rule to the new input, the last-step sequence yields two groups of three numbers whose sums differ by 66.
