The position(s) of how many letters will remain unchanged if each letter in the word COMBINE is arranged in the English alphabetical order?
1
The word COMBINE has the letters, in order: C(1), O(2), M(3), B(4), I(5), N(6), E(7).
Arranging these letters alphabetically gives: B, C, E, I, M, N, O, occupying positions 1 to 7 respectively.
Now compare position by position: position 1 has C (was C, now B) — changed; position 2 has O (now C) — changed; position 3 has M (now E) — changed; position 4 has B (now I) — changed; position 5 has I (now M) — changed; position 6 has N (now N) — unchanged; position 7 has E (now O) — changed.
Only position 6 (letter N) stays the same.
Hence, exactly 1 letter's position remains unchanged.
