Question

Leo estimates that a package weighs 27 pounds. The postal clerk weighs it and finds it weighs 20 pounds. What is the percent error in Leo's estimate?

Answer 1

Answer: 35%

Explanation:

Given

Weight measured by Leo
`W_1=27\ pounds`

Weight measured by the clerk
`W_2=20\ pounds`

Percentage error is

`\Rightarrow \%\ \text{error}=\frac{\text{False value}-\text{Correct value}}{\text{Correct value}}* 100`

Putting values

`\Rightarrow \%\ \text{error}=(27-20)/(20)* 100=35\%`
