CHAPTER 2Coding Decoding

Presented By : saurabh trivedi

A code means arrangement of symbols.

Therefore coding is a method of transforming any

instruction from the given form to the required

form. The coding and decoding is an aid to check

the candidate’s ability to understand the logic

that codes a particular message to read the

message.

Letter Coding

Types of Coding-Decoding

In these questions code values are given to a word in terms of letters. We have to analyze the pattern of the example and follow that pattern to find the answer.

1. Letter Coding

What is it ????

Ø Take the given pair.

Ø Write the position of all letters in given pair.

Ø Try to find the relation between the letters of both part of pair.

Ø Relation may be related to forward or backward order.

Ø Implement the same relation on the given word for required answer.

1. Letter CodingHow to get the code ????

Possible relations on the basis of position of letters in the given words may be-

EXAMPLES

With the help of above two words, we can find out the position of every letter with in a second.

A « Z (A Zad) H « S (High School)

B « Y (B o Y) I « R (Indian Railway)

C « X (CraX) J « Q (Jungle - Queen)D « W (DeW) K « P (KanPur)E « V (E.Ven) L « O (LOve)F « U (FUll) M « N (MaN)G « T (G T road)

With the help of above trick, we can get the opposite letter of any letter.

Opposite Letter
