Question : 38

Total: 73

The weight of a day-old chick was measured to be 0.21g. If the actual weight of the chick is 0.18g, what was the percentage error in the measurement?

15.5%
18.2%
14.8%
16.7%

Solution:

Actual weight = 0.18g

Error = 0.21g - 0.18g

= 0.03g

% error = $\frac{0.03}{0.18} \times 100\%$

= 16.7%
