Direction: A number arrangement machine when given an input of numbers, rearranges them following in particular rule in each step. The following is an illustration of input and of steps 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.
1.  What will the fourth step for an input whose second step is given below?
Step: 765 42 183 289 542 65 110 350  (a)765 42 542 350 183 289 65 110  (b)765 42 542 65 110 183 289 350  (c)765 42 542 65 183 289 110 350  (d)Cannot be determined 

Answer is: CNext step: 765 42 542 65 183 289 110 350
From the last step it is clear that there are two alternating series of numbers: One in descending order and the other in ascending order.
When we go through input to step 1, we find that the largest no. becomes the first and remaining numbers shift rightward. In the next step the smallest no. becomes the second and the rest shift rightward. These two steps continue alternately
until the two alternate series are formed.
2.  What should be the third step of the following input?
Input: 239 123 58 361 495 37  (a)495 37 361 123 239 58  (b)495 37 58 361 123 239  (c)495 37 58 123 361 239  (d)495 37 361 239 123 58 

Answer is: DStep: 495 37 361 239 123 58
From the last step it is clear that there are two alternating series of numbers: One in descending order and the other in ascending order.
When we go through input to step 1, we find that the largest no. becomes the first and remaining numbers shift rightward. In the next step the smallest no. becomes the second and the rest shift rightward. These two steps continue alternately until the two alternate series are formed.
3.  How many steps will be required to get the final output from the following input?
Input: 39 88 162 450 386 72 29  (a)Two  (b)Three  (c)Four  (d)None of these 

Answer is: DNone of these

4.  What should be the last step of the following input?
Input: 158 279 348 28 326 236  (a)348 28 326 158 279 236  (b)348 28 326 236 158 279  (c)348 28 236 158 279 326  (d)348 28 158 326 236 279 

Answer is: AFrom the last step it is clear that there are two alternating series of numbers: One in descending order and the other in ascending order.
When we go through input to step 1, we find that the largest no. becomes the first and remaining numbers shift rightward. In the next step the smallest no. becomes the second and the rest shift rightward. These two steps continue alternately
until the two alternate series are formed.
5.  If the first step of an input is '785 198 32 426 373 96 49', then which of the following steps will be '785 32 426 49 198 373 96' ?  (a)Third  (b)Fourth  (c)Fifth  (d)Second 

Answer is: BFourth
From the last step it is clear that there are two alternating series of numbers: One in descending order and the other in ascending order.
When we go through input to step 1, we find that the largest no. becomes the first and remaining numbers shift rightward. In the next step the smallest no. becomes the second and the rest shift rightward. These two steps continue alternately until the two alternate series are formed.
