## Reasoning: Coding-Decoding Tricks for SSC Exams

Coding-Decoding Tricks for SSC Exams
Coding is a system of signals. This is a method of transmitting information in the form of codes or signals without it being known by a third person.

In question on coding-decoding, a word is coded in a particular way and the candidates are asked to code other word in the same way. The Coding and Decoding tests are set up to judge the candidate's ability to decipher the rule that has been followed to code a particular word/message and break the code to decipher the message.

Here, are some methods/techniques given below to remember the position of English alphabets in forward or backward order.

Trick to remember the position of letters of English Alphabets
1. By using EJOTY and CFILORUX formulae, we can easily remember the position of letters of English Alphabets.
2. By using VQLGB and XUROLIFC, we can easily remember the position of letters of alphabet in reverse order.

3. Backward order position of a letter = 27 - Forward Order position of a letter
e.g. Backward order position of B= 27 -Forward position of B i.e 2
= 27 -2 = 25

4. If the sum of two letters is 27, then both letters are at opposite position of each other.You can remember these pairs of opposite letters by following below given formula:

Have a look at above given trick, you will find that the sum of opposite pair letters is 27. For example:

• D    W = 4 + 23 = 27
• B    Y= 2 + 25 = 27
• G    T = 7 + 20 = 27
• I      R= 9 +18 =27
