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?
A
15.5%
B
18.2%
C
14.8%
D
16.7%
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
Actual weight = 0.18g
Error = 0.21g - 0.18g
= 0.03g
% error = \(\frac{0.03}{0.18} \times 100%\)
= 16.7%
