Coding And Decoding Faster And Better Approach

Coding And Decoding - Faster & Better Approach

Coding and Decoding is one of the most complex chapter in Reasoning section. Even though the section is complex, you can score well if your concepts are clear. Many students find it difficult to solve and as a result they avoid attempting these scoring questions and end up losing some easy and fast marks. Last year some major changes were observed in the pattern of questions related to the topic of Coding-Decoding. Therefore in order to help the aspirants prepare well for this chapter. Here are few important tips to approach the questions of Coding-Decoding with new pattern, in a faster and effective manner. So let’s start.

Let’s start with some examples:

Example (1-3)

Analyse the given information and answer the following questions:

In a certain code language

  • ‘given  time  simple  plan’ was written as ‘@E4  &N4  %N5  #E6’
  • ‘tired  solution  plant  great’ was written as ‘#N8  @D5  %T5  &T5’
  • ‘sick  point  good  turn’ was written as ‘#K4  %D4  @N4  &T5’
  • ‘garden  sister  phone  team’ was written as ‘&E5  #R6  %N6  @M4’

1. What will be the code for ‘translate’?

  • #E8
  • @E9
  • @E8
  • #T9
  • #T8

2. What will be the code for ‘plan’?

  • %N5#E6
  • @E4
  • &N4
  • %N5
  • None of these

3. What does ‘%D4’ stands for?

  • sick
  • turn
  • point
  • good
  • None of these

Way to solve it:

Points to Remember-

  • These types of questions always have a concept which is needed to be found.
  • In this question it is seen that all the steps have all 4 words starting with alphabet G, T, S and P, with that the codes starts with symbols @, %, & and #.
  • So now just the match between the first alphabet and the particular symbol is to be found.
  • The next thing to observe is that the codes are ending with digits. This represents the total alphabets used in each word.
  • Analysing the middle code in the word reflects the last alphabet of their respective word.

Now let’s solve:

Answer 1: B

Step I: First count the alphabets in the word ‘translate’ which is 9, put 9 at the end.
Step II: Put the last alphabet of ‘translate’ before the digit 9 so now the code is E9 till now
Step III: As observed above in all phrase the alphabet ‘t’ is represented by the code ‘@’. So now put ‘@’ at the beginning of the code so the answer is – @E9 that is option b

Answer 2: C

Code for the word ‘plan’ –

Step I: First count the alphabets in the word ‘Plan’ which is 4, put 4 at the end.
Step II: Put the last alphabet of ‘plan’ before the digit 4 so now the code is N4 till now
Step III: As observed above in all phrase the alphabet ‘p’ is represented by the code ‘&’. So now put ‘&’ at the beginning of the code so the answer is – &N4 that is option c

Answer 3: D

Decoded word for ‘%D4’

Step I: The last number is 4 therefore the word consist of 4 word ‘_ _ _ _’
Step II: The Middle code defines the last alphabet of the word which is ‘D’ so put the last alphabet of the word as d, so now the word is ‘_ _ _ d’ till now
Step III: As observed above in all phrase the code ‘%’ is used to represent the alphabet ‘G’. So now put ‘G’ at the beginning of the word so the word is – ‘G _ _ d’ which matches option d, so the word is Good, option d

So now it’s clear how to approach such type of questions, let’s proceed further and give a try to these set of questions.

Example (4-8):

Analyse the given information and answer the following questions:

In a certain code language

  • “login BYJU’s and scroll” was written as “&3d  @6l  *5n  %5s”
  • “scroll for sbi exam” was written as  “@6l  @3i  $3r  #4m”
  • “study exam related notes” was written as “#4m  @5y  !7d  =5s”
  • “read notes for best job” was written as “+3b  !4d $3r =5s  %3t”

4. What will be the code for BYJU’s?

  • *5n
  • &3d
  • %5s
  • @6l
  • None of these

5. What does code ‘!7d’ stands for?

  • read
  • notes
  • related
  • exam
  • study

6. Which of the following code is for “exam BYJU’s sbi job”?

  • !4d $3r @6l &3d
  • +3b #4m %5s =5s
  • %5s +3b #4m @3i
  • %3t @6l @5y !7d
  • None of these

7. Which of the following code is for ‘banking’?

  • %7g
  • $7t
  • &7h
  • one of these
  • can’t say

8. Which of the following code is for ‘probationary’?

  • #12p
  • *13t
  • ^12y
  • %11n
  • $12y

Detailed Analysis of the problem:

  • Read the statements and their given codes properly.
  • Some words are common in the statements given like notes, exam, scroll
  • The codes are common as well – @6l, #4m, =5s.
  • Matching the last alphabet in codes and word we can assign @6l to Scroll; #4m to Exam and =5s to notes.
  • So we can say @ defines S; # defines E and & defines N
  • Now the other special characters for other words are to be decoded.
  • The words like BYJU’s and best, both have same % special characters.
  • Similarly, we analyse and find the following.

 

l b a s f e r n j
* % & @ $ # ! = +

Now let’s solve:

Answer 4: (C)

As we can see in word Byju’s
first letter b = %
total letter = 5
last letter = s
So, code is %5s

Answer 5: (C)

! is code for = r,

7 total Alphabets

d is the last Alphabet.
So the option that matches is ‘related’.

Answer 6: (C)

Exam = #4m,

Byju’s = %5s,

SBI = @3i,

job = +3b
Hence answer is C.

Answer 7: (E)

As we can see in word banking
first letter b = %
total letter = 7
last letter = g
So, code is %7g

Answer 8:(C)

Elimination method is to be used here.

The first Alphabet of probationary is = ‘p’, It has no code assigned yet in any above sentence

In options A, B, D and E, codes used are all already assigned as in table above.

So options A, B, D and E gets eliminated

The option left is C.

So these are the two types following the new pattern of question which was introduced in last year Bank Exams. We hope that this small discussion on Coding-Decoding questions based on new patterns will help you to prepare well for you exams. Wish all the candidates Good Luck!
