Study the following information to
answer the questions given below:
A number arrangement machine when given an input
Of numbers, rearranges them following a particular rule in
each step. The following is an illustration of input and steps
of rearrangement.
`{:("Input : 48 245 182 26 99 542 378 297"),("Step I : 542 48 245 182 26 99 378 297"),("Step II.: 542 26 48 245 182 99 378 297"),("Step III :542 26 378 48 245 182 99 297"),("Step IV :542 26 378 48 297 245 182 99"),("Step V.: 542 26 378 48 297 99 245 182"):}`
(This is the final arrangement and Step V is the last step for this input.)
What will be the fourth step for an input whose second
step is given below ?

(a) 765 42 183 289 542 65 110 350

Options

A. 765 42 542 65 183 289 110 350
B. 765 42 542 350 183 289 65 110
C. 765 42 542 65 110 183 289 350
D. Cannot be determined

Answer

A

Explanation

After analysing the sample sequence, the pattern/rule in
each step for a number arrangement is as follows :
First step : Largest number comes to the left most position.
The remaining numbers shifts rightwards.
Second step : Smallest number shifts to the second
position. The remaining numbers shifts right words as so on.
So, the numbers are arranged as : largest, smallest, second
largest, second smallest, ....... and so on OR in descending
order and in an ascending order alternately.
Note : At each step, position of only. one number is altered.
