A string is 4.8m. A boy measured it to be 4.95m. Find the percentage error.
- \( \frac{5}{16} \)%
- \(1\frac{5}{16} \)%
- \( 3\frac{1}{33} \)%
-
\( 3\frac{1}{8} \)%
- 25%
The correct answer is: D
Explanation
4.95m - 4.8m = 0.15m
\(\frac{0.15}{4.8} \times 100%\)
= \(\frac{25}{8}\)
= \(3\frac{1}{8} %)
