Jambmaths question:
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?
Option A:
15.5%
Option B:
18.2%
Option C:
14.8%
Option D:
16.7%
Jamb Maths Solution:
$\begin{align} & \text{Actual weight}=0.18g \\ & \text{Measured weight }=0.21g \\ & \text{Error}=0.21g-0.18g=0.03g \\ & \text{percent error}=\frac{error}{\text{actual weight}}\times 100 \\ & \frac{0.03}{0.18}\times 100percent=16.7percent \\\end{align}$
