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 alphabet is written in the reverse order and every alpternate letter starting with Y is dropped, which letter will be exactly in the middle of the remaining letters of the alphabet ?

A. M
B. N
C. O
D. M or O
E. None of these
Answer: B . N


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

Canceling every second letter, the above series becomes
Z  X  V  T  R  P  N  L  J  H  F  D B

The middle letter is N.
