Input - Output Arrangements - Examples

In last post we've discussed some shortcuts of the Input - Output arrangements problems of Reasoning section. In this post we shall work with some examples.

Note : To save the space, We are not posting the previous example problem here. So please refer to the example problem here for reference.

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

1 ) Input : Chair Wood 21 42 59 Height Bench 78.

      How many steps will be required to complete the rearrangement?

                 1. Three

                 2. Four

                 3. Five 

                 4. Six

                 5. None of the above.

Solution : write the first letters of the given problem.

• Step 1 : 78 C W 21 42 59 H B
• Step 2 : 78 B C W 21 42 59 H
• Step 3 : 78 B 59 C W 21 42 H
• Step 4 : 78 B 59 C 42 W 21 H
• Step 5 : 78 B 59 C 42 H 21 W
• Step 6 : 78 B 59 C 42 H 21 W

So, according to the logic, step 6 is the last step for this input (Numbers are in descending order and words are in alphabetical order in this step 6). So 6 Steps will be required to complete the rearrangement. So the answer is option 4.



2)  Input : When You 22 Special 31 16 47 Town

             Which of the following steps will be the last but one?

• 1. 4th
• 2. 6th
• 3. 5th
• 4. 7th
• 5. Non of the above

Solution : 

• Step 1 : 47 W Y 22 S 31 16 T
• Step 2 : 47 S W Y 22 31 16 T
• Step 3 : 47 S 31 W Y 22 16 T
• Step 4 : 47 S 31 T W Y 22 16
• Step 5 : 47 S 31 T 22 W Y 16
• Step 6 : 47 S 31 T 22 W 16 Y

So, the answer is Step 5. So option 3 is correct.



3) Step 4 of an input is : 74 Again 69 Call 17 32 Horse Desk 

      Which of the following is definitely the input?

• 1. Again Call 74 69 17 32 Horse Desk
• 2.  74 Call Again 17 69 Horse 32 Desk
• 3.  Call 74 Again 69 17 32 Desk Horse
• 4.  Cannot be Determined
• 5.  None of these

Sol : As we have already discussed, this is the case of arrangement. So, the previous steps cannot be determined with certainty. We cannot estimate the exact input.

4) Step 3 of an input is :

82 Brown 74 Sugar Hobby Lady 32 49

Which of the following will be step 6?

• 1.  82 Brown 74 Hobby 49 Sugar Lady 32
• 2.  82 Brown 74 Hobby 49 Lady Sugar 32
• 3.  82 Brown
  Hobby  74 Hobby 49 Lady 32 Sugar
• 4.  Cannot be determined
• 5.  None of these.

Sol : Step 3 is 82 Brown 74 Sugar Hobby Lady 32 49, And  we can find that first 3 words are in a proper order. So just strike them off with pencil and work with remaining words.

• Step 4 : H S L 32 49
• Step 5 : H 49 S L 32
• Step 6 : H 49 L S 32

So, option 2 is correct.

Note: If you don't have enough time and you want to take risk then just see the answers. They've given the step 3, so there are chances that the first 3 letters wont change (in this case). So obviously the answer will be either option 1 or option 2. But this method is not suggestible.  

5) Input : Goal Team Ask 12 92 85 42 Sound.

Which of the following will be the step 4 ?

• 1.  92 Ask 85 Goal 42 Sound 12 Team
• 2.  92 Ask 85 Goal 42 Sound Team 12
• 3.  92 Ask 85 Goal 42 Team 12 Sound
• 4.  92 Ask 85 Goal 12 42 Sound
• 5. None of These

Sol : Input : G T A 12 92 85 42 S

• Step 1 : 92 G T A 12 85 42 S
• Step 2 : 92 A G T 12 85 42 S
• Step 3 : 92 A 85 G T 12 42 S
• Step 4 : 92 A 85 G 42 T 12 S

So the answer is option 3.

Thats all for now friends. Tomorrow we shall discuss some more problems of this type. Good Day and Happy Reading :)
