In this type of questions, you are given alphabets from A to Z. The position of a letter is given in the form of a puzzle. The candidate is required to find yhis letter. However, sometimes a random letter series is given and the candidate is required to find out how many times a letter satisfying the conditions specified in the question, occurs.
The following question is based on the following alphabet series.
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
If the letters of the given alphabet interchange positions, so that A takes the place of Z and Z takes the place of A; B takes the place of Y and Y takes the place of B and so on, what will be the thirteenth letter from the right ?
The new alphabet series is :
Z Y X W V U T S R Q P O N
M L K J I H G F E D C B A
Counting from the right in the above series i.e., A, the thirteenth letter is M.
