A bricklayer measured the length of a wall and obtained 4.10m. If the actual length of the wall is 4.25m, find his percentage error.
- A.
3 9/17% - B.
3 27/41% - C.
15% - D.
35 5/17% - E.
36 24/41%
Correct Answer: Option A
Explanation
Error = 4.25 – 4.10 = 0.15
% error = (frac{0.15}{4.25} times 100%)
= (frac{15}{frac{17}{4}} = frac{15 times 4}{17})
= (3frac{9}{17} %)
