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 alternate letter starting with Y is dropped, which letter will he exactly in the middle of the remaining letters of the alphabet?
1) M
2) N
3) O
4) M or O
5) None of these

Options

A. M
B. N
C. O
D. M or O

Answer

B

Explanation

The new alphabet series obtained on reversing the order
`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 `
The new alphabet series on cancelling every second letter becomes: `Z X V T R P ul(N) L J H F D B `
Number of letters = 13 (an odd number)
So, middle letter = `("Number of letters")/2 = (13 + 1)/2 = 7`
`[because "an odd number"]`
Therefore, the middle letter between Z and B is the seventh letter from any end. i.e., N.
