This topic is all about alphabets and different patterns used to form a new word.

Solving Coding Decoding in Fictitious Language problems look hard but are among the easiest to solve. They are usually pretty straightforward and are thus scoring.

It is very important to know the numeric position of each alphabet, in normal order starting from 1 as well as in reverse order i.e. starting from A=26, B=25…..


Go through the following table and remember the positions of the alphabets.

To quickly get the reverse position value of a particular letter you can subtract its original position’s numeric value from 27.

Coding and Decoding questions can be divided into following types:

  • Letters
  • Numeric
  • Symbols
  • Group of Words

Letters and Numeric

In letters and Numeric type, there can be many combinations but some expected and common types are explained with example.


In a certain language, if SUNSHINE is coded as TVOTIJOF then how will MOON be coded:

  1. NPPQ
  2. NPPO
  3. PPON
  4. NQQP

Answer: NPPO

+1 in all the letters.

This is one type of question. In a similar way for the same type, there can be +2, +3 or there can be -2, -4, etc.


In a certain language, if WRONG is coded as GNORW then how will RIGHT be coded:

  1. HIRGT
  2. SJHIU
  3. GHIRT
  4. None of the above

Answer: GHIRT

If you observe carefully then the coded word GNORW has same letters as in the original word. So, if we go by elimination method then option b is eliminated here itself. Now if we look at the pattern of coding, it can be observed that all the letters of WRONG are arranged in Ascending Order. So, in the same way, RIGHT will be coded as GHIRT. There can be the same type of question asked but instead of ascending, the words can be in descending order.
