Question 14

20% of 40 is 8.

To determine what percent of 40 is 8, we can use the formula (part/whole) x 100. Here, the part is 8 and the whole is 40, which results in (8/40) x 100 = 20%.

A) 8%

This option is incorrect because 8% of 40 would equal 3.2, not 8. To find 8% of a number, you multiply 0.08 by that number, which does not yield the correct result in this case.

B) 2%

This option is also incorrect as 2% of 40 would be 0.8, which is significantly less than 8. Therefore, it does not represent the correct percentage of 40 that results in 8.

C) 20%

This is the correct answer. Calculating 20% of 40 involves multiplying 40 by 0.20, which equals 8. Thus, 8 is indeed 20% of 40.

D) 0.05%

This option is incorrect because 0.05% of 40 would amount to 0.02, which is far less than 8. Hence, it cannot represent the percentage of 40 that results in 8.

Conclusion

The correct answer is 20% since it accurately reflects the calculation that 8 is 20% of 40. All other options fail to represent the correct relationship between 8 and 40, highlighting the importance of precise percentage calculations.
