Multiple choice

Directions: An electronic device, when fed with the numbers, rearranges them in a particular order following certain rules. The following is a step by step process of rearrangements, for the given input of numbers.

Input : 5 28 12 74 3 11 31 42 Step I : 74 5 28 12 3 11 31 42 Step II : 74 3 5 28 12 11 31 42 Step III: 74 3 42 5 28 12 11 3 Step IV: 74 3 42 5 28 11 12 31 (For the given input, step IV is the last step)

If the step IV is as given below, which of the following will be the input?

Step IV: 48 03 22 7 12 25

  1. 03 25 12 48 22 07

  2. 13 25 48 12 22 07

  3. 03 48 25 12 22 07

  4. Cannot be determined

D Correct answer
Explanation

The pattern of the arrangement of steps of the given input suggests that the given input is split into two sections - one for even numbers and other for odd numbers. Then, these numbers are arranged in such a way that even numbers are arranged in a descending order and odd numbers are arranged in an ascending order. We cannot determine the input for the given step because the exact placement of the number in input cannot be known. As a result, options (1) and (2) both reflect the probable input.
