    The document discusses input-output questions as a type of reasoning aptitude test. It provides 3-4 sentences summarizing the key aspects: 1) Input-output questions test the ability to identify patterns in arrangements of words or numbers and determine the rule being followed. 2) Students must carefully observe at least two steps to deduce the pattern of changes between each step. 3) The document then provides examples of input-output questions and their solutions, demonstrating different types of rules like reordering, shifting positions, or mathematical operations.

     The questions based on Input-Output are


    being the easiest topic in reasoning aptitude.
     The questions based on Input-Output aims to
    judge how quickly one can identify the rule
    applied in the arrangement of given Input Line of
    words or numbers cited as sample.
     In these type of question students are need to
    find out the specific pattern in the given
    arrangement and then determine the desired
    output step.
     These problems are not very difficult but they
    are time consuming if individual is not aware of
    the short tricks.
     Students can attain expertise in this type of
    questions through adequate practice.
    Some Important Tricks:
     First of all, Students should monitor the given
    Input Line of words or numbers carefully and the
    last step of rearrangement so that they can
    identify the changes appeared in various steps of
    rearrangement.
     Students should observe at least two consecutive
    steps to identify the changes appeared in every
    step.
     At last compare the input, the last step and any
    one of the middle Steps. It will enable to identify
    the rule of arrangement quickly.
    Input –Output:
    These are the problems that test your
    thinking skills. You will be given some input and a
    machine (its working) using some examples. You
    have to study this working and accordingly process
    the data given to you.

    In the questions related to this topic, you are


    expected to be the “machine”. You would be told
    what processing has to be done. You would be
    given the input, your job would be give the output
    in accordance to the input.
    In the topic of input output there are primarily four
    types of operation that can be asked in a particular
    question. The four operations are as follows:

    1. Ordering input according to given criteria, e.g.


    alphabetically, in increasing/decreasing order etc.
    2. Mathematical Manipulations on the output
    which would in this case obviously be numerical. The
    operations could be doubling, squaring, adding.
    3. Shifting or Interchanging positions of
    characters/alphabets/words etc., in the input
    according to questions e.g. ‘shift 1st character to
    last’ or ‘interchange 1st & last’ etc.
    4. Others like making an alphabet capital, replacing
    alphabet by corresponding number etc.
    So, which out of these is being used can be
    decided as:

     If words (of the input) do not change in the


    output after an operation, the operations is
    either reordering or shifting. In this case check
    for rearrangement first, if it is not the operations
    performed then check for shifting next.
     If words (of the input) do change in the output,
    the operation is either Mathematical (if numbers
    are used) or fall into category of other operations
    (if alphanumeric data is used).
    Example 1:

    A computer rearranges a particular input using


    some operations 01, 02, 03, and 04.

    Input : I have long waited for your arrival.


    Step 01: arrival long have waited for your I
    Step 02: long arrival waited have for I your
    Step 03: Your waited arrival have for I long
    Step 04: Waited your have arrival for long I

    If step 4 gives “I know you will not come back”


    what step will have “you back I come not will
    know”?
    Solution:
    Since words remain unchanged here, so this is case of
    either rearrangement or shifting. So, let us number
    each word
    I = 1, have = 2, long = 3, waited = 4, for = 5, your =
    6, arrival = 7
    Input: 1 2 3 4 5 6 7
    Step 01: 7 3 2 4 5 6 1
    Step 02: 3 7 4 2 5 1 6
    Step 03: 6 4 7 2 5 1 3
    Step 04: 4 6 2 7 5 3 1
    So, the logic being following is as follows:-
    Step 01 = Swap 1st & last; 2nd & 3rd
    Step 02 = Swap 1st & 2nd, last two & 3rd and 4th
    Step 03 = Swap 1st & last, 2nd & 3rd.
    Step 04 = 1st & 2nd, last two, & 3rd and 4th.
    Since after two steps operations again repeat and
    hence you can guess the 5th, 6th, 7th steps.

    Step 04: I know you will not come back


    Step 05: back you know will not come I
    Step 06: You back will know not I come
    Step 07: Come will back know not I you
    Step 08: Will come know back not you I
    Step 09: I know come back not you will
    Step 10: Know I back come not will you
    Step 11: You back I come not will know
    Hence step 11 is the answer.
