There are 10 letters between H and S and there is no letter which lies exactly in the middle.

Example: Which letter should be ninth letter to the left of ninth letter from the right, if the first half of the given alphabet is reversed?

Answer:

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 first half of the alphabets is reversed then the new series is:

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

The ninth letter from the right is R.

The ninth letter to left of R is E.

Example: If all the letters of this series are written in reverse order then which letter will be 3rd to the left of the letter which is 18th from your right ?

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

Answer:

On writing the letters of the given series in reverse order we get :

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

Now 18 + 3 = 21 (Right to left)

So, 21st letter from the right is F.
