How to Solve New Coding-Decoding Problems in Bank PO Exams 2017 – A Step by Step Guide



Hello and welcome to exampundit. Reasoning is a very important section in
the banking examinations. And you are all well aware that the pattern of
questions asked in the reasoning section has changed a lot. So today, we are
sharing an article on how to solve the new pattern coding –decoding.
3 STEP APPROACH FOR SOLVING
CODING-DECODING-
1. Have a look at the words and codes
given.
2. Translate the codes.
3. Deduce the probable codes.
Now after reading these 3 steps you might
be thinking if it’s so easy to decode the codes then why 
you have been finding
it difficult to do so in the examination hall. Yes, it is easy but when paid
attention. 
The reason why you found it a little difficult in the examination
hall was you were not well acquainted with the new pattern.  The previous pattern coding-decoding asked in
the exams was based on the method of “elimination” but the new pattern is based
on ‘’translating codes”. So let’s take an example to learn the new pattern with
the above 3 step approach.


Example-
Inventions the college world needs          3#7     [email protected]      
[email protected]       7#8       5%4
Yuvraj is my favourite player                      9#2       2?4         6$1         6*2       [email protected]    
Study this from Manorama Yearbook       8^4      
5?8         8&2        [email protected]     
4!2
Decoding using the 3 step approach-
Step 1- A general look clearly shows that
each code has a number both in the beginning and in the end and in between
there is a symbol.
Step 2- A more deeper analysis for
translating the codes.
Taking the first line in consideration

Inventions the college world needs     3#7    
[email protected]     [email protected]     7#8    
5%4
We clearly observe that the number 5 in the
beginning of a code is written twice which means that any two words have
relation with number 5. Here in this, the number 5 represents the total number
of alphabets in a word (world and needs both the words have 5 alphabets).
So, the codes that can be deduced by this
much analysis-
Inventions- [email protected]
The- 3#7
College- 7#8
World- [email protected] or 5%4
Needs- [email protected] or 5%4
Also, number 8 is written twice in the end
of a code. So we’ve to deduce some relation. But taking only a single line in
consideration we are not able to derive any relation. So proceed further.
Taking second line in consideration
Yuvraj is my favourite player     9#2    
2?4     6$1     6*2    
[email protected]
Codes that can be deduced by above
analysis-
Yuvraj- 6$1 or 6*2
Is- 2?4 or [email protected]
My- 2?4 or [email protected]
Favourite-9#2
Player- 6$1 or 6*2
Taking last line in consideration
Study this from Manorama Yearbook     8^4    
5?8     8&2     [email protected]    
4!2
Codes that can be deduced by above
analysis-
Study- 5?8
This- [email protected] or 4!2
From- [email protected] or 4!2
Manorama- 8^4 or 8&2
Yearbook- 8^4 or 8&2
It must be noted that in “Inventions” the
symbol in the code is ‘@’ which is also a symbol either in the code for “world”
or for “needs”. If we look carefully, then Inventions and Needs both have
alphabet “s” at the end which hence means that the symbol in the codes is for
the last alphabet in the word. And hence more codes can be deduced.
Needs- 
[email protected]  so automatically ‘world’ will
be coded as- 5%4
Is- [email protected] 
so automatically ‘my’ will be coded as- 2?4
This- [email protected] 
so automatically ‘From’ will be coded as- 4!2
Now the codes
for ’Manorama’, ‘Yearbook’, ‘Yuvraj’ and ‘Player’ are still unclear. Since the
total number of alphabets, last alphabet has already been considered in codes
as the initial number and the symbol respectively. So we may consider either
the first alphabet or the middle alphabet 
etc which can form some sort of relation with the last number in the
code to decode the remaining codes.
When we consider
‘Manorama’ which can be coded as either 8^4 or 8&2. If we consider the
first alphabet ‘M’ the numeric value of which is 13. So it is a possible that
1+3 has been summed up and hence 4 in the end of the code. But then as per this
possible deduction the numeric value in the end in the code for ‘Yearbook’ will
be 7 which isn’t there. So, we have to look for some other possible deduction.
The reversal for
‘M’ is ‘N’. If we consider the numeric value of ‘N’, it is 14. The value 4 may
come when we multiply 1 and 4. When we consider ‘Y’ in ‘Yearbook’, the reversal
for which is ‘B’. The numeric value of the same is 2. So, the codes for ‘Manorama’
and ‘Yearbook’ are 8^4 and 8&2 respectively. Similarly the codes for
‘Yuvraj’ and ‘Player’ are 6*2 and 6$1 respectively.
Step 3- Hence all
the codes have been decoded. The first numeric value represents the number of
the alphabets in the word, symbol in place of the last alphabet of the word and
the last numeric value represents the value of reversal. If the numeric value
of reversal is a two-digit number then the digits are multiplied and if a
single-digit number then it is written as it is.
The overall process takes a minute or two
depending on the practice. This has been elaborated just for making things
clear to you.
