Question

How many meaningful four-letter English words can be formed using the first, second, third, and fifth letters of the word "SCHOOL" (when counted from left to right), using each letter only once in each word?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

Answer:

A. 1

Word: SCHOOL

Letters with positions:

1. S

2. C

3. H

4. O

5. O

6. L

We are to use the 1st, 2nd, 3rd, and 5th letters:

Letters: S, C, H, O

We must form four-letter meaningful English words using each letter once.

Now check possible arrangements of S, C, H, O:

Possible meaningful words include:

• COSH (to hit or strike; also slang usage)

• HOCS (not a valid word)

• SHOC / SCH O / etc. not valid

• COS H / HOSC / etc. not valid

Only valid standard English word:

• COSH

Total meaningful words = 1

Final Answer: 1
