15. If 4 is x percent of 16, what is x?

Answer: D

Explanation:

x is 25

To find what percentage 4 is of 16, we can use the formula \( x = \frac{4}{16} \times 100 \). This calculation shows that 4 is 25% of 16.

A) 01-Apr

This option is incorrect as it does not represent a percentage value. The question requires a numerical percentage, and "01-Apr" does not fit within the context of the problem.

B) 4

Choosing 4 as the answer is incorrect because it does not reflect the percentage of 4 in relation to 16. Instead, it simply states one of the values rather than its percentage.

C) 16

This option is incorrect as it presents the total value rather than the percentage. The question is asking for the percentage that 4 is of 16, not the total itself.

D) 25

This option is correct because when calculating the percentage of 4 in relation to 16, we find that \( \frac{4}{16} \times 100 = 25 \). This confirms that 4 is indeed 25% of 16.

Conclusion

The answer of 25 definitively reflects the correct percentage relationship between 4 and 16. All other options either misrepresent the nature of the question or fail to provide a valid percentage, confirming that D is the only correct answer.
