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 IV: 552  36  388  58  307  255  192  109
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) Second
b) 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) 42
b) 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.
