Coding and Decoding is the easiest section when it comes to scoring.it takes the minimum amount of time if you know some of the common types of questions and tricks.

It can be of 5 types:

i)alphabets

ii)numeric

iii)symbols

                                                                                                                      Alphabets

A       B      C     D     E     F     G      H     I      J      K      L                O      P      Q      R      S      T       U      V      W      X      Y      Z

1        2       3      4      5     6      7      8     9    10    11     12    13    14     15   16      17     18     19     20    21   22      23      24      25    26

* An important point to keep in mind 'Sum of Position of an alphabet and its reverse is always equal to 27'.

For e.g. A+Z=1+26=27

              C+X=3+24=27

*To remember the alphabets and its reverse, form a story like this

AhraZ   is a BoY who is CompleX by nature and he loves to DraW pictures of EnVironment in his FaltU time. he GoT a painting from HarSh,(his friend) which was IrregulaR in shape and has a picture of Jacket-Quilt. Harsh wanted him to KeeP the painting. He also gifted him shoes of LottO and he looked like gentleMaN after wearing it.

                                                                                                                         

                                                                                                                     Numeric

Types:

i)Based on the position of the alphabet.

e.g.   If FLOW is coded as 6121523, then BAT=2120

ii)Based on reverse position of alphabet.

e.g If Flow is coded as 2115124, then BAT=25267

iii)Based on the Sum of the position of alphabets.

e.g.If Flow is 56,BAT=23

                                                                                                                                         Symbols

Some special characters will be representing the alphabets or numbers.

Trick:

I)identify the repeating letters and symbols in a word.

II)Identify the repeating letters in different words.

Remember, The letter sequence and symbol sequence need not be the same.

e.g.if FOOD is written as '$*@*',DOOR =?

Here,* is repeating so, O=*, D=$/@. Here comes the need for options. Go to Option and check if anyone Contains a strange symbol,$/@ and *

Good Luck!
