Question on: WAEC Mathematics - 1994

A string is 4.8m. A boy measured it to be 4.95m. Find the percentage error.

A
\( \frac{5}{16} \)%
B
\(1\frac{5}{16} \)%
C
\( 3\frac{1}{33} \)%
D
\( 3\frac{1}{8} \)%
Ask EduPadi AI for a detailed answer
Correct Option: D

4.95m - 4.8m = 0.15m

\(\frac{0.15}{4.8} \times 100%\)

= \(\frac{25}{8}\)

= \(3\frac{1}{8} %)
