Double Side Arrangement Problems

Arranagement Type:- In this type of questions, the words or the numbers are arranged as per a fixed pattern. This pattern can be an alphabetical order in case of words, it can be an increasing or decreasing order in case of numbers.

How to identify whether the given input is of shifting or arrangement?

The basic difference between them are that the shifting goes on endlessly and at last it is written and so on and in arrangement arranging ends as soon as the order intended is achieved I.e., arrangement type of questions has last step.

Arrangement is of two types.

1. Single side arrangement. 2. Double side arrangement.

Double Side Arrangement : From the above examples we have seen the type of arrangement now let's see the type of logic as it can be alphabetical, numerical, alpha-numerical etc. Let's understand it with the below diagram.

Based on vowel

Based on consonant

Based on increasing number

Based on decreasing number

Based on number of letters in given word

Based on odd number

Based on even number

Based on alphabetical order

Based on reverse alphabetical order

Based on square of number

Based on cube of number

Tricks Regarding Arrangement:

In questions on arrangement when any step is given and input is asked answer will be "cant be determined".

To identify the pattern in question prefer the last step.

In this type of question when words all of sudden get transformed in number then the numbers most of the time comes from the place value of first or last letter of the word.

In arrangement problems, the contents of an earlier step can never be determined with certainly.

Illustration: Study the following information carefully and answer the questions given below. A number arrangement machine, when given a particular input, rearranges it following a particular rule. The following is the illustration of the input and the steps of arrangement.

Input: 39 55 19 20 37 41 68 53

Step I: 19 39 55 37 41 68 53 20

Step II: 19 37 55 41 68 53 20 39

Step Ill: 19 37 41 68 53 20 39 55

Step IV: 19 37 41 53 20 39 55 68

Step V: 21 34 43 50 22 36 57 65

desired arrangement is obtained. As per rules followed in the above steps, find out the appropriate step for the given input.

Input: 25 58 47 33 23 73 64 61

Which of the following is step V of the given input?

A. 25 27 61 63 70 30 44 62 B. 25 44 63 70 27 30 62 61

C. 25 44 63 70 27 30 60 61 D. 25 44 63 70 27 60 61 30

E. None of these

Answer: C

Solution: on analysing the steps we find that

Step I-Step IV: Prime numbers are arranged in ascending order from the left end and other numbers are arranged from the right end.

Step V: +2, -3, +2, -3.

Input: 25 58 47 33 23 73 64 61

Step I: 23 58 47 33 73 64 61 25

Step II: 23 4758 73 64 61 25 33

Step IlI: 23 47 61 73 64 25 33 58

Step IV: 23 47 61 73 25 33 58 64

Step V: 25 44 63 70 27 30 60 61

Hence the correct option is C.

Question : 2

A word and number arrangement machine when given an input line of words and numbers rearranges them following a particular rule in every step. The following is an illustration of input and rearrangement. Input: 79 create history 88 imagined 94 every 63 leader 96 Step I: 88 79 create history imagined 94 63 leader 96 every Step II: 88 79 96 history imagined 94 63 leader every create Step III: 88 79 96 history imagined 94 63 every create leader Step IV: 88 79 96 94 imagined 63 every create leader history Step V: 88 79 96 94 63 every create leader history imagined Step V is the last step of the arrangement. Following the same pattern solve the given input. Input: never 42 leaved 39 important object 53 46 anyplace 74 How many steps will be required to complete the given input?
A. III	B. IV	C. V	D. VI
Right Option : C

Explanation

Input: 79 create history 88 imagined 94 every 63 leader 96
Step I: 88 79 create history imagined 94 63 leader 96 every
Step II: 88 79 96 history imagined 94 63 leader every create
Step III: 88 79 96 history imagined 94 63 every create leader
Step IV: 88 79 96 94 imagined 63 every create leader history
Step V: 88 79 96 94 63 every create leader history imagined
Step V is the last step of the arrangement.

Here in the above input the numbers and the words are arranged in the different manner.

Arrangement of numbers : Here the numbers are arranged as the number whose sum of the digits is highest is arranged on the extreme left in the Step I after that the number whose sum of the digits is second highest is arranged the right of the number arranged in step I.

Number	Digits Sum
88	16
79	16
96	15
94	13
63	9

As the digits sum of both ‘88’ and ‘79’ is same, then the highest number i.e. 88 will be arranged first.

Number	Arrangement Step
88	Step I
79	Step II
96	Step III
94	Step IV
63	Step V

As the arrangement of the numbers follows the left to right pattern therefore it might be possible that some numbers are arranged automatically.

Arrangement of words : Here the words are arranged as the word having highest number of letters is arranged on the extreme left in the Step I after that the word having second highest number of letters is arranged the right of the word arranged in step I.

If the sum of the digits of two numbers is same then number which highest will be arranged first.

Word	Number of Letters
every	5
create	6
leader	6
history	7
imagined	8

As the number of letters in both ‘create’ and ‘leader’ are same, then the word which comes first according to dictionary i.e. ‘create’ will be arranged first.

Word	Arrangement Step
every	Step I
create	Step II
leader	Step III
history	Step IV
imagined	Step V

As the arrangement of the words follows the right to right pattern therefore the number of steps required to complete the arrangement will not be not be less than the number of words in the given input.

Now, the given input:

Input: never 42 leaved 39 important object 53 46 anyplace 74

Numbers:

Number	Digit Sum	Arrangement Step
39	12	Step I
74	11	Step II
46	10	Step III
53	8	Step IV
42	6	Step V

Words:

Word	Number of Letters	Arrangement Step
never	5	Step I
leaved	6	Step II
object	6	Step III
anyplace	8	Step IV
important	9	Step V

As the number of letters in both ‘leaved’ and ‘object’ are same, then the word which comes first according to dictionary i.e. ‘leaved’ will be arranged first.

Arrangement:

Input: never 42 leaved 39 important object 53 46 anyplace 74
Step I: 39 42 leaved important object 53 46 anyplace 74 never
Step II: 39 74 42 important object 53 46 anyplace never leaved
Step III: 39 74 46 42 important 53 anyplace never leaved object
Step IV: 39 74 46 53 42 important never leaved object anyplace
Step V: 39 74 46 53 42 never leaved object anyplace important
Step V is the last step of the arrangement.

Hence the correct option is C.
