Directions (Q 1-5): Study the following information carefully to answer the given questions.
A number arrangement machine when given an input line of numbers rearranges them following a particular rule in each step. The following is an illustration of input and rearrangement.
Input: 58 255 192 36 109 552 388 307
Step I: 552 58 255 192 36 109 388 307
Step II: 552 36 58 255 192 109 388 307
Step III: 552 36 388 58 255 192 109 307

Step V: 552 36 388 58 307 109 255 192
This is the final arrangement and Step V is the last step for this input.

a) Secondb) Sixth
c) Fourth
d) Fifth
e) Third
5. If the step of an input is “795 208 42 436 383 106 59” then which number would be the fourth from the right end in step II?
a) 42b) 208
c) 106
d) 436
e) None of these
Solution
The numbers are arranged in such a way that the largest number becomes the first number and the remaining numbers shift rightwards. In the next step the smallest number becomes the second number and the remaining numbers shift rightwards. These two steps continue alternately until two alternate series are formed.
