Question

The distance between two places was $250km$. It was measured as $260km$, find the percentage error?

Answer 1

$\Rightarrow$ The distance between two places $=250km$

$\Rightarrow$ The measured distance $=260km$

$\Rightarrow$ Error $=(260-250)km=10km$

$\Rightarrow$ $\%error=\frac{10}{250}\times 100$

$\therefore$ $\%error=4\%$
