In this article, we will share how to solve the new type of questions from Coding Decoding which will be very helpful for your SBI PO Exam. We will not cover the simple examples where you can find the codes with the help of repeating articles. Based on the new pattern introduced by the IBPS, we will start explaining the techniques with the help of sample questions:
-
Type 1
Question: Study the information below and answer the following question. In a certain code language, the following sentences are written as:
`India will play tests` is written as ‘ #Y4, $S5, @L4, !A5’
`Against South African team` is written as ‘ %N7, ^H5, $M4, %T7’
`Under captain Virat Kohli` is written as ‘(T5,) I5, *N7, &R5’
`After almost twelve years’ is written as ‘%T6, _S5, %R5, $E6’
The code for the word ‘captain’ is:
- (T5
- ) I5
- *N7
- &R5
Solution:
Approach
In the codes that you can see, there are three digits. The codes are not necessarily in the same order as in the sentences on the left. You need to analyze each digit one by one. Let’s start with a numeric digit. In the first sentence on the left, the number of alphabets in each word are:
- India – 5
- Will – 4
- Play – 4
- Tests – 5
Which are also found in the code on the right.
Now start shortlisting the options. The two contenders for the digit 5 are: $S5 and !A5 which represent India and Tests, not necessarily in the same order.
Now coming to second digit of the code, we analyze that they are ‘S’ and ‘A’ which are also the last alphabet of Tests and India correspondingly.
Therefore, the code for India is !A5 and for Tests is $S5.
Using the same logic, we get the code for ‘Will’ as @L4 and for ‘Play’ as #Y4
Now we are left with only first digit of the code to analyze.
Looking further, we found that there are many symbols repeated in the code. Most repeated is % symbol. Symbol $ appears twice only, once in the first line for the word ‘Tests’ (= $S5) and once in the last line in the code ‘$E6’.
Decoding ‘$E6’, we have last digit as 6, that means the word should be of 6 digits : either ‘Almost’ or ‘Twelve’. Now the middle digit in ‘$E6’ is E, therefore the last alphabet must be E which is in ‘Twelve’. Therefore, the code ‘$E6’ corresponds to ‘Twelve’.
Now the similarity between ‘Tests’ (= $S5) and ‘Twelve’ =(‘$E6’) is that the first alphabet of both start with T and the corresponding code is $.
Using the same technique, we get the following table:
| Alphabet | I | W | P | T | A | S | U | C | V | K | Y |
| Corresponding Symbol | ! | @ | # | $ | % | ^ | & | * | ( | ) | _ |
Therefore in this code:
- The first element is symbol that represent first letter of that word.
- Middle element is a letter that is last letter of word.
- The last element of code is number that represents number of letters in the word.
Based on this, the code for word ‘captain’ is *N7.

Type 2
Question: Study the following information to answer the given question:
In a certain code language,
‘Most safety high level’ is written as ‘8*Y, 7?L, 6#H, 6%T’
‘Made in India project’ is written as ‘9@T, 7!A, 6%E, 4!N’
‘Setlist new home’ is written as ‘5*T, 6#E, 6?T, 5&W’
‘Large sale post interval’ is written as ‘6@T, 10!L, 7?E, 6*E’
Find the code for the word ‘Person’:
- 8*E
- 6*N
- 8@N
- 6@E
- None of these
Solution:
Using the approach as mentioned in the above example, we have the following in this code:
- The first digit of code is number that represent number of letters in the word + 2.
- Middle element is a symbol that represent first letter of that word.
- The last element is alphabet that represent last letter of that word.
Based on this, the code for word ‘captain’ is 8@N.
-
Type 3
Question: Study the following information to answer the given question:
In a certain code language,
‘ONE BOX ZIP’ is written as ‘8&G, 6?E, 2#F’
‘SIX FOX ZOO’ is written as ‘1&F, 6#F, 8#F’
Based on this, find the code for ‘JIR’
Solution:
Approach
In the codes that you can see, there are three digits. The codes are not necessarily in the same order as in the sentences on the left. You need to analyze each digit one by one. Let’s start with numeric digit.
The numeric digits in the code are 8,6 and 2, which are not related to any square or cube. So we need to establish a logic here. Let’s see the position of letters in the words given one by one
| Alphabet | Position | Sum of Column 2 (Position) | Corresponding Alphabet based on column 3 (sum of column 2) |
| O | 15 | 1+5=6 | |
| E | 5 | 5 | E |
| B | 2 | 2 | |
| X | 24 | 2+4=6 | F |
| Z | 26 | 2+6=8 | |
| P | 16 | 1+6=7 | G |
Therefore:
- Now decoding of ‘ONE’ becomes = 6?E
- ‘BOX’ becomes – 2#F
- ‘ZIP’ becomes – 8&G
Each symbol in the middle fo the 3 digit code is unique and corresponds to the middle digit of the word, i.e.
- N=>?
- O=>#
- I=>&
Using the same logic, to find the code for JIR:
J’s Position in the alphabet is 10, therefore sum of digits is 1+0=1, therefore first letter is 1
We also know that I=>&, therefore second letter is &
R’s Position in the alphabet is 18, therefore sum of digits is 1+8=9, therefore alphabet at 9th position is I,
- JIR becomes 1&I
