Coding & Decoding
Reasoning Tricks
 These type of questions are generally asked in Banking Exams
and certain entrances like KLEE, CLAT etc. which have a
reasoning part.
 These questions are very easy to answer but you should know
the strategy behind it.
 It takes a little time if you follow the strategies. We are going to
discuss about the strategy
Coding & Decoding : Scoring Part
Types of Coding Decoding
There are 6 different types of coding decoding.
 Number Coding
 Letter Coding
 Mixed Coding
 Mixed Number Coding
 Decoding
 Symbols Coding
We are going to discuss about Symbol coding & Decoding here

.
Symbol Coding
“In this type of questions either alphabetical code values are
assigned to symbols or symbols are assigned to alphabets.
Q.1 In a certain code "ECAM" is written as "@$*&" and
"IRA" is written as "?^*". How can "ICECREAM" be written in that
code?
Solutions:
E : @
C: $
A: *
M: &
I: ?
R: ^
ICECREAM : ?$@$^@*&
Ans:
Try this:
1. In a certain code HEAT is written as ? * $ @
and FINGER is written as  £ • & * #. How
can FATHER be written in that code?
2. In a certain code BODE is written as @ $ * ?
and EAT is written as ? • £ How can DEBATE
be written in that code?
2.
Decoding
Let’s start with the second set of slides
In these questions code values are assigned to a word or a group
of words and the candidate is required to find out the original
words.
Q. In a certain code if FLOWER is written as EKNVDQ, what will be
written as GNTRD?

EULGH will be coded as?
2. If DHSX is coded as City than RSZSD is
coded as?
