Reasoning Input output Short Tricks

Today I am sharing Reasoninga Input Output technique to solve questions quickly.

# Patterns

1. Pattern Based On Shifting 
2. Pattern Based On Arrangement 
3. Pattern Based On Mathematical Operation
4. Miscellaneous Approach Or Other Patterns

1. Based On Shifting

In this pattern ,you will find the elements are shifting from one place to other

Important Note:

• In shifting problems, the previous step of any step can possibly be determined,so we can move in backward or reverse order which is not possible in some of the other type of problems.

How to solve Problems Based on Shifting

Lets take an Example

Input: Boy Crazy Guy Other Help Charm

Step 1. Boy Other Guy Crazy help Charm

Step 2. Boy Other Help Crazy Guy Charm

Step 3. Charm Other Help Crazy Guy Boy

Step 4. Charm Crazy Help Other Guy Boy

Step 5. Charm Crazy Guy Other Help Boy

Step 6. Boy Crazy Guy Other Help Charm

Shifting of element can easily be understood by marking them equivalent to number like

Boy = 1,Crazy = 2, Guy = 3, Other = 4, Help = 4, Charm = 5.

Input can be written as 1 2 3 4 5 6

Step 1,  2 and 4 interchanged
Step 2. 3 & 5 interchanged
Step 3. 1 & 6 interchanged
Step 4. Step 1, 2 & 3 are repeated again.

2.  Based on Arrangement

Rules :

1. Previous Step can never be determined. Let we have given Step VI & then ask to find Step V or IV or III ,so this is clear gives you the answer 'Cannot be determined' 
2. Let Total No. Of element or words or numbers  in input is 8. So take n = 8 then Maximum step can be made through this input is ( n - 1).It will only happen in the case of Arrangement.
3. To find particular step ( Let x) for any input , logically pick 1st x alphabetical word or numbers in increasing order and just place them before the remaining word or numbers. This is the case Apply when given Input is an  'Increasing Order' & For Decreasing Order last x word or numbers should be picked. We will do this through example later in this article.   

Different types of Arrangements:

1. From Left
2. From Right
3. Left-Right Alternate Arrangement
4. Increasing/Decreasing Arrangement of Numbers
5. Left-Right Alternate Arrangement of Numbers
6. Arrangement of word & Number simultaneously

1. From Left 
   
2. From Right
   
3. Left- Right Alternate Arrangement
   
4. Increasing/Decreasing Arrangement
   
5.  
   
6. Arrangement of Word & Numbers Simultaneously

Case 1.

Case 2.

Case 3.

Case 4.

 

Example:

Input vain istanbul tomorrow mind blowing gesture of the elbow 

Step 1. blowing vain istanbul the mind gesture of elbow

Step 2. blowing elbow vain istanbul the mind gesture of

Step 3. blowing elbow gesture vain istanbul the mind of

Step 4. blowing elbow gesture istanbul vain the mind of

Step 5. blowing elbow gesture istanbul mind vain the of

Step 6. blowing elbow gesture istanbul mind of vain the

Step 7. blowing elbow gesture istanbul mind of the vain

1. Input ' is you are again famous on this' Find the Step 3.

a) again are famous is you on this b) on this you is famous are again c) this on you is famous areagain

d) famous this on you is are again e) None of these

2. If given, Step 4 'option pen rose Seema tape yolk ' , what will be the input? 

a) pen option rose tape Seema yolk b) yolk Seema tape rose option pen 

c) tape Seema yolk rose option pen d) Cannot be determined e) None of these 

3. Input 'no gum to sum fame game;Find the Step 1.

a) game no gum to sum fame b) gum no to sum fame game c) game gum no to sum fame

d) Cannot be determined e) None of these

4. Input ' He is a great Indian cricketer'.Find out the last step for this input.

a) 7

b) 6

c) 4

d) Cannot be determined 

e) None of these

5. Input 'when men ten gain rain'.What would be the second step for this input?

a) gain when men ten rain b) gain men when ten rain c) rain ten men when gain

d) Cannot be determined e) None of these

Sol:

1. Applying Rule 3. Pick Alphabetically 3 words in forward order ( again, are , famous)

and place them before the remaining word that will give you :

Step 3. again are famous is you on this 

2.Applying Rule 1. Hence Cannot be determined

3.Applying Rule 3. Step 1 : fame no gum to sum game Option e is correct.

 

4. Applying Rule 2. Total No of words = 6. n=6 then n-1 which is 6-1=5

Hence total No of Step can be made is 5. So Option a),b) & c) is wrong.

Now Apply Rule 3

 Input : He is a great Indian cricketer.

In alphabetical order :  A=1 , Cricketer =2, Great =3 , He = 4, Indian =5, Is= 6

Clearly After removing 1,2,3&6 ( four words) the remaining words come in order

So, Total Steps = 4, Total words Removed = 4 & Last Step = 4.

Step 4 : A cricketer great he indian is.

5. Applying Rule 3 

Step need to find = 2, Total Word = 2

Input : When men ten gain rain

Now pick the word alphabetically it will be men gain,Now placed them  at front in ascending order before the other words like this : gain men and Now other words are when ten rain.

So it became Step 2: gain men when ten rain.

3. Based on Mathematical Operation

It will be better understood through an example

So lets take an example

Input :  31 45 87 54 25 68

Step 1	4	9	15	9	7	14
Step 2	3	20	56	20	10	48
Step 3	961	2025	7569	2916	625	4624
Step 4	29791	91125	658503	157464	15625	314432
Step 5	6.5	9	17.4	10.8	5	13.6
Step 6	4	9	6	9	7	5
Step 7	33	47	89	56	27	70
Step 8	26	40	82	49	20	63
Step 9	93	135	261	162	75	204
Step 10	8	18	30	18	14	28
Step 11	2	1	1	1	3	2
Step 12	9	81	225	81	100	196

Step 1: Digit sum of input.
Step 2. Product of the digits of input
Step 3. Square of the each number of the input
Step 4. Cube of the each number of the input
Step 5. Each number of the input is divided by 5
Step 6. Keep adding digits till they are converted into single digit
Step 7. Each number of the input + 2
Step 8. Each number of the input - 5
Step 9. Each number of the input * 3
Step 10. Digit's sum of each number of input * 2
Step 11. Difference between digits of  each number of the input
Step 12.  ( Digit sum of each number of input )²

4. Misc. Problems

There is no fixed pattern in regard of statement. Statement under this category will come before you as a real surprise.Such question are complete mind game.

Step I.    Interchanged the first and last digit of the input.

Step II.   Fix the zero after the first digit of the given input

Step III. 1st digit becomes last in two-digit numbers while middle digit becomes the 1st digit in three-digit numbers

Step IV. Last digit of the given input is removed 

Step V.   Just specify the zero at the end of the digit of the given input.
