# solve machine input output questions in reasoning quickly #3- trick for solving input output questions quickly

we have previously discussed about the first two types of machine input-output questions in reasoning in our previous posts. First learn them and then move on to this post –trick #3

you can read part #1 here
or you can go to see the sitemap on top of the site where all links of shortcuts,tips and tricks are given.
so this time we will discuss about

changing positions of words/numbers as per the set pattern

In this type of questions, the candidate is required to follow a pattern according to the position of the letter/words in the given input. The candidate is given a question in which some kind of word arrangement is given like a machine is given some input and it is processing some output for that input.
Here is an example
Find out the logic behind the question and answer the question then.
A machine writes the following steps when given an input as given below.
Input-   man’s mood varies with time and environment
Step-1   varies with man’s mood environment and time

Step-2   and time environment mood man’s varies with
Step-3   environment time and varies with mood man’s
Step-4   and varies environment time man’s mood with

Now as per the pattern of the machine given above
Find out the question given below?
If a machine is given input as  ‘everyone were aware about their intimate friendship’.  What will be step 2 according to above arrangement.

Solution:  now write down numbers below each alphabet in the given question’s arrangement as given below:
Input-   man’s(1) mood(2) varies(3) with(4) time(5) and(6) environment(7)

Step-1   varies with man’s mood environment and time
The above step becomes
Step-1   3              4              1              2              7              6              5
Step-2   and time environment mood man’s varies with
Step 2 becomes
Step 2-  6             5              7              2              1              3              4

So we found out the step 2 arrangement from the given example. So apply this step 2 arrangement to the question asked
Input-   everyone were aware about their intimate friendship
1              2              3              4              5              6              7
Step 2 based on above question arrangement   6              5              7              2              1              3              4
Step-2   intimate their friendship were everyone aware about
