Question 3

1 is 5 percent of 20.

To determine what number 1 is 5 percent of, we can set up the equation 1 = 0.05 * x, where x is the number we want to find. Solving this gives us x = 20, confirming that 1 is indeed 5 percent of 20.

A) 5

Option A is incorrect because 5 cannot be the number from which 1 is 5 percent. If we calculate 5 percent of 5, we get 0.25, not 1.

B) 20

Option B is correct as it accurately reflects that 1 is 5 percent of 20. This can be easily verified by calculating 5 percent of 20, which equals 1, thus satisfying the condition of the question.

C) 25

Option C is incorrect because if we take 5 percent of 25, we obtain 1.25, which is greater than 1. Therefore, 1 cannot be 5 percent of 25.

D) 50

Option D is also incorrect as 5 percent of 50 equals 2.5, which is significantly higher than 1. Thus, 1 cannot be 5 percent of 50.

Conclusion

The correct answer is 20 because it directly satisfies the condition that 1 is 5 percent of that number. All other options fail to meet this criterion, as they either yield results greater than or less than 1 when calculating their respective 5 percent values.
