Input Output Tricks

इनपुट-आउटपुट से संबंधित समस्याएं, अक्सर विभिन्न प्रतियोगी परीक्षाओं में पूछी जाती हैं। वे बहुत कठिन नहीं हैं, लेकिन हल करने के लिए एक अच्छा समय लेते हैं या कभी-कभी छात्र समय लेने के कारण उन्हें हल करने का प्रयास नहीं करते हैं। लेकिन विषय की उचित समझ आपको विश्वास दिलाती है कि ऐसी समस्याएं उतनी कठिन और समय लेने वाली नहीं हैं जितनी वे लगती हैं।

The question on input output reasoning is a game of intelligence. But if you know about input output tricks (इनपुट आउटपुट ट्रिक्स), then you can solve the input output reasoning question easily.

Input Output Tricks (इनपुट आउटपुट ट्रिक्स)

Types of Problems

• Problems of shifting
• Problems of arrangement
• Problems of mathematical operation

Problems of shifting

Example:-

Input: Blue Cat Good Other Have Cake

Step 1: Blue Other Good Cat Have Cake

Step 2: Blue Other Have Cat Good Cake

Step 3: Cake Other Have Cat Good Blue

Step 4: Cake Cat Have Other Good Blue

Step 5: Cake Cat Good Other Have Blue

Step 6: Blue Cat Good Other Have Cake

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

Blue = 1, Cat = 2, Good = 3, Other = 4, Have = 5, Cake = 6

Input can be written as

1          2          3         4        5        6

Blue    Cat     Good   Other  Have   Cake

Step-1: 2 and 4 interchanged

Step-2: 3 and 5 interchanged

Step-3: 1 and 6 interchanged

Step-4: 2 and 4 interchanged

Step-5: 3 and 5 interchanged

Step-6: 1 and 6 interchanged

Problems of arrangement

Word Arrangement from Left Side

Example:-

Input: mango tango orange banana pear

Step I: banana mango tango orange pear

Step II: banana mango orange tango pear

Step III: banana mango orange pear tango

Here, we start arrangement from the word that comes 1st in the dictionary; then comes the word coming 2nd in the dictionary, then comes the word coming 3rd in the dictionary and so on.

Word Arrangement from Right

Example:-

Input: Name Fame Game Shame Jam

Step I: Name Game Shame Jam Fame

Step II: Name Shame Jame Game Fame

Step III: Shame Name Jam Game Fame

In this case, the arrangement starts from right side. The word coming 1st in the dictionary comes at the 1st position from right. At the 2nd position from right comes the word coming 2nd in the dictionary and the process goes on till the arrangement gets completed.

Problems of mathematical operation

Example:-

Input:     44    35      18      67      22      28      36

Step I:     36    27      10      59      14      20      28

Step II:   16    15      8        42      4        16      18

Step III: 132  105     54      201     66      84     108

Step IV:  50    41      24      73      28      34      42

Step V:   8      8        9        4        4        1        9

Step VI:  64    64      81      169     16      100     81

Step VII: 20    19      12      46      8        20      22

In this case,

Step I: Minus 8 from each number of the input

Step II: Product of the digits of each number of the input

Step III: Each number of the input is multiplied by 3

Step IV: Add 6 to each number of the input

Step V: Keep adding the digits of each number of the input till they are converted into single digit

Step VI: Square of digit sum of each number of input

Step VII: Add 4 to each number of step II

Input Output Reasoning Tricks

Step 1: First of all, observe the given input line of words or numbers and the last step of rearrangement, so that candidate may get an idea about the changes effected in various steps of rearrangement.

Step 2: In order to know what changes have been made in each step, observe two consecutive steps carefully.

Step 3: Now, correlate the input, the last step and anyone of the middle steps. This will enable you to identify the rule of arrangement.

Step 4: In shifting problems, it is possible to determine the previous/earlier steps including input. We can proceed/move backward or in reverse direction in shifting problems.

Step 5: In shifting problems for convenience, we assign numeric value to given words.

Example:

Input: shop 17 table 20 53 oven desk 39

Step I: 17 shop table 20 53 oven desk 39

Step II: 17 table shop 20 53 oven desk 39

Step III: 17 table 20 shop 53 oven desk 39

Step IV: 17 table 20 shop 39 53 oven desk

Step V: 17 table 20 shop 39 oven 53 desk

Step V is the last step of the rearrangement.

As per the rule followed in the above steps, find out in each of the following questions the appropriate step for the given input.

Question: Input: 89 bind 32 goal house 61 12 joy

How many steps will be required to complete the arrangement?

(a) Four        (b) Five

(c) Six          (d) Seven

(e) None of these

Solution: (c)

Explanation:

In the first step, the smallest number comes to the leftmost position and the remaining line shift rightward. In the next step the word that comes last in the alphabetical order occupies the second position from the left and the remaining line sift rightward. This goes alternately till all the number are ranged in ascending order and all the words in reverse alphabetical order at alternate positions.

Input: 89 bind 32 goal house 61 12 joy

Step I: 12 89 bind 32 goal house 61 joy

Step II: 12 joy 89 bind 32 goal house 61

Step III: 12 joy 32 89 bind goal house 61

Step IV: 12 joy 32 house 89 bind goal 61

Step V: 12 joy 32 house 61 89 bind goal

Step VI: 12 joy 32 house 61 goal 89 bind

Example:

Input: base 35 or gone 62 49 87 ahead

Step I: 87 base 35 or gone 62 49 ahead

Step II: 87 ahead base 35 or gone 62 49

Step III: 87 ahead 62 base 35 or gone 49

Step IV: 87 ahead 62 base 49 35 or gone

Step V: 87 ahead 62 base 49 gone 35 or

Step V is the last step of the rearrangement.

As per the rule followed in the above steps, find out in each of the following questions the appropriate step for the given input.

Question: Input: 14 35 When they came 61 48 home

How many steps will be required to complete the rearrangement?

(a) Four        (b) Five

(c) Six          (d) Seven

(e) None of these

Solution: (c)

Explanation:

In the first step, the largest number comes to the first position and the remaining line shift rightward. In the next step the word that comes first in the alphabetical order goes on to occupy the second position pushing the rest of the shift rightward. This goes alternately till all the numbers are arranged in a descending order and all the words in alphabetical at alternate positions.

Input: 14 35 when they came 61 48 home

Step I: 61 14 35 when they came 48 home

Step II: 61 came 14 35 when they 48 home

Step III: 61 came 48 14 35 when they home

Step IV: 61 came 48 home 14 35 when they

Step V: 61 came 48 home 35 14 when they

Step VI: 61 came 48 home 35 they 14 when
