Given- actual weight of a sand bag -40 kg- error in weight -40-8 kg-x2234- percentage error -40-8-x2212-4040-xD7-100-x2234- Error -2-Hence- option D is the correct answer-

The weight of a sand bag is $40 k g$ . In a hurry it was weighted as $40.8 k g$ . The error percentage is:
$0.5 %$
$1 %$
$1.5 %$
$2 %$

Given, actual weight of a sand bag $= 40$ kg, error in weight $= 40.8$ kg
$∴$ percentage error $% = \frac{40.8 - 40}{40} \times 100$
$∴$ Error $= 2 %$
Hence, option $D$ is the correct answer.
