Mapping original letters to preceding letters
B тЖТ A, L тЖТ K, A тЖТ Z, R тЖТ Q, I тЖТ H, N тЖТ M, G тЖТ F. The transformed set is {A, K, Z, Q, H, M, F}.
Sorting the new set of letters
Arranging {A, K, Z, Q, H, M, F} in alphabetical order results in {A, F, H, K, M, Q, Z}.
Identifying the target position
Counting from the right: 1st is Z, 2nd is Q, 3rd is M. Thus, the letter M is the 3rd from the right.
A: F is 6th from the right (2nd from the left), not 3rd from the right. B: J is not present in the transformed set of letters. D: K is 4th from the right (4th from the left), not 3rd from the right.
C is correct because the transformed set sorted alphabetically is A, F, H, K, M, Q, Z, where M occupies the third position from the right.
When asked for the Nth position from the right in a series of length L, simply calculate the (L - N + 1)th position from the left to save time.
