Answer:
24%
Step-by-step explanation:
Error = | actual value - estimated value |
[tex]error \: percentage = \frac{error \: value}{original \: value} \times 100[/tex]
From the question actual value = 75, estimated value = 57. Therefore,
error = 75 - 57 = 18.
Hence,
% error = 18 / 75 × 100
= 18 / 3 × 4
= 6 × 4
% error = 24%
