Explanation:

The reasoning section of almost every competitive examination contains questions on Alphabet Reasoning.In this topic, questions are asked relating to positions of English alphabets. This topic is very important from exam point of view. So you need to memorize the positions of the alphabets so that you can handle each and every question based on this topic. Let us discuss various types of alphabet reasoning:

1. THE ALPHABET: The English alphabet contains 26 letters, as given below:

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

From A to M, the alphabet completes the first 13 letters that is the first half, while the second half starts from 14th letter that is it starts from N and ends at Z.

(First Alphabetical Half) A to M ⇒ 1 to 13

(Second Alphabetical Half) N to Z ⇒ 14 to 26

2. Concept of EJOTY: The positions of alphabets can be remembered with the help of this simple concept, you can easily find out the position of any letter without much effort. But it is advisable that you learn the positions of different letters in the alphabet.

E J O T Y

5 10 15 20 25

For example, we are asked to find the 24th letter from the left side of the alphabet. We already know that the 25th letter from the left-hand side is Y, now we need to find letter before Y and that is X. By using this simple method, we can easily find out the position of any letter in the alphabet. Memorizing the positions & sequence of letters is a basic to solve any questions of this type, so you should try to memorize these positions. For this particular reason, you should practice EJOTY. Write down the names of ten of your friends & do as given below:

Let us take an example of name RAVI. With the help of EJOTY, we know that the letter R stands for number 18, A stand for 1, V stands for 22, I stands for 9. Adding all these numbers, we get (18+1+22+9). This is a very good way to remember the positions of all the letters in the alphabet.

3. Positions of letters from Right Hand Side (RHS): Many a times we get questions in the tests that ask us the position of a letter from the right hand side. Although we are in a habit of counting from the left side of the alphabet & not from the right hand side of the alphabet. We are discussing this by taking an example and then we will make a mathematical formula.
