Q:

If the position of the first letter of English alphabet is interchanged with the position of the fourteenth letter, second letter with fifteenth letter, and so on, in such a way that M is interchanged with Z, then which of the following letters will be 7th to the right of 13th letter from the right?

A) U	B) G
C) H	D) I

Answer & Explanation Answer: C) H

Explanation:

It means that the first half of the alphabet is interchanged with second half of the alphabet. After making changes, nth letter from the left will be (n + 13)th letter of original series, ie English alphabet; If n is less than 14. But if n is more than 13, nth letter from left will be (n - 13)th letter from left.
In the given equation, we have to find out (13 - 7 =) 6th letter from right => (26 - 6 + 1 =) 21st letter from the left. Hence, required letter's position is more than 13; therefore the required letter is (21 - 13 =) 8th letter from left of original series, ie H.
