Question

The weight of a sand bag is $40kg$. In a hurry it was weighted as $40.8kg$. The error percentage is:

• A. $1\%$
• B. $0.5\%$
• C. $1.5\%$
• D. $2\%$

Answer 1

The correct option is D $2\%$

Given, actual weight of a sand bag $=40$ kg, error in weight $=40.8$ kg

$\therefore$ percentage error $\%=\frac{40.8-40}{40}\times 100$
$\therefore$ Error $=2\%$
Hence, option $D$ is the correct answer.
