Show answer & explanation
Correct answer: B
There are 26 letters in the English alphabet.
The 21st letter from the right equals the 6th letter from the left, which is F (because 26 − 21 + 1 = 6).
The 10th letter from the right equals the 17th letter from the left, which is Q (because 26 − 10 + 1 = 17).
Letters between F and Q are: G, H, I, J, K, L, M, N, O, P.
Count them or use positions: number between = 17 − 6 − 1 = 10.
Therefore, there are 10 letters between the two given letters. None of the provided answer choices (6, 8, 7, 9) is correct.
