Last updated: October 28, 2012 by Sarbjit+
Most competitive exams have a dedicated section of Reasoning or Mental Ability. Many of our students and readers find in difficult to solve questions based on Mental Aptitude. We will try and provide you material to help you understand some concepts with these "How To" articles.
Today, we will talk about Coding - Decoding questions.
Coding - Decoding
A code is a ‘system of signals'. Coding can be used to send secret messages. Coding is to convert the message into some signals & Decoding is to convert it into the original form.
In almost all entrance exams, Coding Decoding questions are asked in the mental ability section. Today we will discuss major type of coding.
Example: If MADRAS is coded as NBESBT. How is BOMBAY coded in that code?
(e) None of these
Explanation: Now you can see that in the above example each letter in the word MADRAS is moved one step forward to obtain the corresponding letter of the code. M is coded as N, A is coded as B and so on.
M A D R A S
N B E S B T
So code for
B O M B A Y is
C P N C B Z
Likewise code may be moved one step backward also.
Example: If T A P is coded as S Z O Then code: F R E E Z E
Ans: E Q D D Y D
Letters may be moved alternately one step forward & one step backward or vice - versa.
Order of letters may be reversed.
