All of the following are ways to write 25 percent of N EXCEPT A. (0.25)N B. 10025 N C. 41 N D. 25N
The correct answer and explanation is:
Correct Answer: B. 10025 N
Explanation (approx. 300 words):
When expressing 25 percent of N, we are finding 25% × N, which is equivalent to multiplying the number NN by 0.25 (since 25% = 25/100 = 0.25). So, any correct representation of “25 percent of N” must reflect this multiplication.
Let’s examine each choice:
A. (0.25)N
This is correct.
It directly means 0.25 × N, which is exactly how we write 25 percent of N in decimal form.
B. 10025 N
This is incorrect and does not represent 25 percent of N.
The expression “10025 N” is ambiguous and has no mathematical meaning related to percent. It could be interpreted as a multiplication of 10025 × N or possibly a typo. Importantly, nothing about this suggests 25 percent. Therefore, this is the correct choice for the “EXCEPT” question.
C. ¼ N (written as 41 N in the question)
Though “41 N” looks like a typo, it likely means 1/4 N.
Since 25 percent is the same as 1/4, this is also a correct representation of 25 percent of N.
D. 25N
This can be interpreted as 25 × N, which means 2500 percent of N — not 25 percent.
But if the original question meant to write (25/100)N or 0.25N, then it would be correct. However, if it literally says “25N”, then this would be 25 times N, which is far more than 25 percent. This could also be an incorrect choice, depending on formatting.
Conclusion:
Among all options, B (10025 N) clearly has no valid connection to expressing 25 percent of N, while the others are at least reasonable approximations depending on interpretation. So, B is the best answer to the question asking for the exception.
