Directions: Determine how many meaningful English words can be formed using the specified letters from the given word, using each letter only once in each word. If no valid word can be formed, mark your answer as '$'. If more than three valid words can be formed, mark your answer as '#'. Otherwise, choose the option corresponding to the exact number of words formed.
How many meaningful words can be formed using the 2nd, 5th, 8th, and 9th letters from the left end of the word DOCUMENTATION?
Correct Answer :
2
Solution :
The correct answer is 2.
Let us identify the specified letters from the word DOCUMENTATION by counting their positions from the left end:
1st letter: D
2nd letter: O
3rd letter: C
4th letter: U
5th letter: M
6th letter: E
7th letter: N
8th letter: T
9th letter: A
10th letter: T
11th letter: I
12th letter: O
13th letter: N
The 2nd, 5th, 8th, and 9th letters are O, M, T, and A respectively.
Now, using each of these four letters (O, M, T, A) exactly once, we can form the following meaningful English words:
1. ATOM
2. MOAT
No other valid four-letter English word can be formed using these four letters.
Therefore, exactly 2 meaningful words can be formed.
