Chapter 6.4, Problem 21IP

To determine

To find: Percent error.

Answer to Problem 21IP

Percent error is $-2.343\%$

Explanation of Solution

Given information:

Entered value $=1000$ kilobytes

Actual value $=1024$ kilobytes.

Percent error $=\frac{A}{O}\times 100$

Where

  $A=$ Absolute value.

  $O=$ Actual value.

From given information

Entered value $=1000$ kilobytes

Actual value $=1024$ kilobytes.

Absolute value = Entered value $-$ Actual value.

  $\begin{array}{l}\Rightarrow A=1000-1024\\ \Rightarrow A=-24\end{array}$

Therefore,

Percent error $=\frac{-24}{1024}\times 100$

  $\Rightarrow$ Percent error $=\frac{-2400}{1024}$

  $\Rightarrow$ Percent error $=-2.343$

So, Percent error is $-2.343\%$ .
