Approach to Solve the Questions Based on Input-Output Reasoning

Firstly, aspirants need to read the given input and steps carefully to analyze the pattern being followed.

Secondly, while going through each step try to figure out how the shifting of the given words or numbers takes place.

Thirdly, try to solve such questions on a rough sheet of paper as solving such questions verbally can be more confusing.

Fourthly, do not skip any step given in the question as skipping a step would lead you to the wrong output and you would end up marking the wrong answer.

Fifthly, once the pattern is determined, try to apply the same for the given input that needs to be solved.

Types of Questions Based on Input Output Reasoning

Following are the types of questions asked from the input-output concept-

1. Shifting-Based Machine Input

2. Single Shifting-Based Machine Input

3. Double Shifting Based Machine Input

4. Operation-Based Machine Input

5. Box-Based Machine Input

Now let’s understand all of the types of input-output questions in detail -

1) Shifting-Based Machine Input

In this type of input-output-based question, shifting of numbers, words or letters takes place.

This is further classified into two types-

a) Single Shifting-Based Machine Input

In this type of input-output-based question, shifting of numbers, words or letters takes place from only one end, i.e., either from the left end or from the right end.

Example: Study the information given below and answer the following question:

Input: Treat Mouse Mobile Games Bag Box

Step I: Bag Treat Mouse Mobile Games Box

Step II: Bag Box Treat Mouse Mobile Games

Step III: Bag Box Games Treat Mouse Mobile

Step IV: Bag Box Games Mobile Treat Mouse

Step V: Bag Box Games Mobile Mouse Treat

And Step V is the final step.

Based on the pattern followed above, find the output for the given input:

Input: House Colony Yellow Bear Red White

1. Colony Yellow Bear Red White House

2. Red White House Colony Yellow Bear

3. Red White Yellow Bear House Colony

4. Bear Colony House Red White Yellow

5. House Red White Yellow Bear Colony

Solution:
Here, the words given in the input are arranged in alphabetical order in the given steps from left to right. One word at a time is rearranged in the given steps.

Similarly, the step-by-step arrangement of the given input is as follows-

Step I: Bear House Colony Yellow Red White

Step II: Bear Colony House Yellow Red White

Step III: Bear Colony House Red Yellow White

Step IV: Bear Colony House Red White Yellow

So, the output for the given input is Bear Colony House Red White Yellow. Hence, the fourth option is correct.

b) Double Shifting Based Machine Input

In this type of input-output-based question, shifting of numbers, words or letters takes place from both ends.

Example: Study the information given below and answer the following questions:

Input: 32 pigeon 46 89 sparrow peacock hen 80 92 22 parrot crow

Step I: crow 32 pigeon 46 89 sparrow peacock hen 80 92 parrot 22

Step II: crow hen pigeon 46 89 sparrow peacock 80 92 parrot 22 32

Step III: crow hen parrot pigeon 89 sparrow peacock 80 92 22 32 46

Step IV: crow hen parrot peacock pigeon 89 sparrow 92 22 32 46 80

Step V: crow hen parrot peacock pigeon sparrow 92 22 32 46 80 89

Step VI: crow hen parrot peacock pigeon sparrow 22 32 46 80 89 92

And Step VI is the final step.

Based on the pattern followed above, find the output for the given input:

Input: pasta 98 plate 89 spoon 10 15 fork knife 36 49 glass

1. plate 89 spoon 10 15 fork knife 36 49 glass pasta 98

4. fork glass knife pasta plate spoon 10 15 36 49 89 98

5. 10 15 fork knife 36 49 glass pasta 98 plate 89 spoon

Solution:
Here, the words given in the input are arranged in alphabetical order in the given steps from the left end and the numbers are arranged in ascending order from the right end. Two rearrangements are taking place in the given steps.

Similarly, the step-by-step arrangement of the given input is as follows-

Step I: fork pasta 98 plate 89 spoon 15 knife 36 49 glass 10

Step II: fork glass pasta 98 plate 89 spoon knife 36 49 10 15

Step III: fork glass knife pasta 98 plate 89 spoon 49 10 15 36

Step IV: fork glass knife pasta plate 98 89 spoon 10 15 36 49

Step V: fork glass knife pasta plate 98 spoon 10 15 36 49 89

Step VI: fork glass knife pasta plate spoon 10 15 36 49 89 98

Step III: 135924 135796 579248 357468 135268 379246

Step IV: 24 31 35 33 25 31

Step V: 24 25 31 31 33 35

Step V is the last step of the above arrangement as the intended arrangement is obtained. As per

the rules followed in the given steps find out the appropriate steps for the given input:

3. 27 35 69 33 33 27

4. 27 53 31 48 33 27

Solution: The pattern is as follows-

In step I, the digits of the numbers given in the input are reversed.

In step II, the numbers are arranged in ascending order.

In step III, first, the odd digits are arranged in ascending order followed by the even digits

in ascending order of each number.

In step IV, the sum of the digits of the numbers is present.

In step V, the numbers are arranged in ascending order.

Following the above pattern, step IV of the given input will be 21 35 31 33 33 27. Hence, the

first option is correct.

3) Box-Based Machine Input

In this type of input-output-based question, the numbers would be given in boxes and certain mathematical operations are performed on the set of the numbers given in the boxes.

Example: Study the given information carefully and answer the given questions.

An input-output is given in different steps. Some mathematical operations are done in each step.

As per the rules followed in the steps given above, find out the appropriate steps for the given input.

Q1. What will be the sum of the digits of the number of step IV?

A) 3 B) 9 C) 5 D) 2

Solution:

The pattern is as follows-

In step I, the digits of the numbers given in the input are divided by 2.

In step II, the digits of the first number and the digits of the second number of step I are added and

combined. Similarly, the digits of the third and fourth numbers and the fifth and sixth numbers of step I are

added and combined.

In Step III, the first and the second numbers are added and the second and third numbers given in Step II

are added.

In step IV, the number is the difference between the first and second numbers of step III.

Following the above pattern, the sum of the digits of the number of step IV of the given input will be 2 + 1 = 3. Hence, the first option is correct.
