Given:
The number of candies in the jar is 413.
The actual number of candies in the jar was 493.
The percentage error is calculated as,
[tex]\text{Percentage error=}\frac{|\text{ approximate value- Exact value|}}{\text{Exact value}}\times100[/tex]The percentage error for the given data is,
[tex]\begin{gathered} \text{Percentage error}=\frac{|413-493|}{493}\times100 \\ =\frac{80}{493}\times100 \\ =16.23\text{ \%} \end{gathered}[/tex]Answer: percentage error is 16.23 % ( up to 2 decimal)
