Question

Each of the letters in the word STUDENT is arranged in alphabetical order. How many letters are there in the English alphabetical series between the letter that is second from the left and the one that is fourth from the right in the new letter-cluster formed?

1. A. 17
2. B. 13 (Correct answer)
3. C. 11
4. D. 15

Correct Answer

Option B — 13

Detailed Solution & Explanation

The correct answer is 13.

Key Points

• Arrange STUDENT alphabetically: D, E, N, S, T, T, U. The letter second from the left is E (position 5 in the alphabet); the letter fourth from the right is S (position 19).
• Count the letters strictly between them: F, G, H, I, J, K, L, M, N, O, P, Q, R = 13.
• Do the two-step carefully — first re-sort the word, then count positions from the correct ends before measuring the alphabet gap.
