# How to solve Input Output? (Tips & Tricks)

By Avik Sarkar|Updated : July 6th, 2016

In Banking and Insurance exams, five questions are frequently asked from this topic.

1. Shifting In this type of problems, we usually shift the given words (or numbers) of the given input as per fixed pattern. Generally letters and numbers are placed in ascending or descending order, one at each step. The following example shows how this is done:

For e.g. –

Input: Ram person is a great

Step I: a Ram person is  great
Step II: a great Ram person is
Step III: a great is Ram person
Step IV:  a great is person Ram
Step IV is the last step.

In the above arrangement, in each step one word is arranged one step at a time from left to right in ascending alphabetical order.

2. Arrangement– In this type of questions, the words or the numbers are arranged as per a fixed order. The pattern of ordering could be:

1. Alphabetical in case of words (beginning). Ex: plot,  round

2. Alphabetical in case of words (end). Ex: round, plot

3. Increasing or decreasing in case of numbers.

4. According to number of consonants or vowels in each word.

5. According to the words beginning with consonants or vowels.

6. According to even numbers or odd numbers.

7. According to the words ending with consonants or vowels. Ex: plate, bruno

The arrangement types of questions also consist of various types of categories such as; Single shifting arrangement, Double Shifting arrangement.

(I). Single shifting arrangement

In single shifting arrangement, one word or numbers are arranged either in a left or right side in each step. The process continues till the last steps. For e.g:

Input: 22 care 59 never 87 sold 15 land house 43

Step I: care 22 59 never 87 sold 15 land house 43
Step II: care 15 22 59 never 87 sold land house 43
Step III: care 15 house 22 59 never 87 sold land 43
Step IV: care 15 house 22 land 59 never 87 sold 43
Step V: care 15 house 22 land 43 59 never 87 sold
Step VI: care 15 house 22 land 43 never  59 87 sold
Step V: care 15 house 22 land 43 never  59 sold 87
Step V is the last step of the given input.

After observing the arrangement, we can conclude that in first step; word is arranged in left side in ascending order and in second step number is arranged in left side in increasing order. The process continues till the last step.

Special Note:

After arranging word “house” in step III our next arrangement will be “22”, but is already come in its place without arranging, so we will not count 22 in our next step and move to word “land” which will be arrange step IV.

The same case is repeated in step VI, after arranging the word “never” our next arrangement will be “59”, but is already come in its place without arranging, so we will not count 59 in our next step and move to word “sold” which will be arrange step V.

3. Double shifting arrangement – In double shifting arrangement, two words (or numbers) are arranged either in a left side or right side in each step. The process continues till the last steps. For e.g:

Input: more 40 great and 60 74 will

Step I: 74 more 40 great 60 will and
Step II: 74 60 more 40 will and great
Step III: 74 60 40 will and great more
Step IV: 74 60 40 and great more will
Step IV: is the last step of the arrangement of the above input as the intended rearrangement is obtained.

After observing the arrangement, we can conclude that in each steps; the numbers are arranging in decreasing order on the left end and words are arranging in alphabetic order on the right end. The process continues till the last steps.

Special note:

In arrangement problems, we cannot find previous step. If Step IV or Step V is given and in question and it was asked to find the previous step, we cannot find it. So, our answer will be cannot determined.

### Points to Remember

For arranging the logic of arrangement you are advised to follow a certain things.

Have a glance at the first and the last step. This will give you a rough idea of what really happened in between the steps.

1. Have a quick glance at every step to know how this is being carried out.

2. Rearrange the given input step by step or if required move from final step to the input.

3. You should check from both left and right hand side, so that you don't miss any corner.
