Question

How many meaningful English words can be formed with the letters A, D, E and R using all the letters, and each letter only once in each word?

• A. None
• B. One
• C. Two
• D. Three

Answer 1

The Correct Option is D

To form meaningful English words using the letters A, D, E, and R with each letter used exactly once, we begin with arranging them to see possible words. Here are the steps:

1. Identify possible arrangements of A, D, E, and R.
2. There are 4! (factorial) = 24 possible permutations of these four letters.
3. Among these arrangements, we need to check which ones form meaningful English words.

By examining the combinations, the meaningful words we can create are:

1. DEAR
2. DARE
3. READ

Therefore, there are three meaningful English words that can be formed using all the letters A, D, E, and R, each used once.

Answer: Three
