A boy estimated his transport fare for a journey as N190 instead of N200. Find the percentage error in his estimate
95%
47.5%
5.26%
5%
Correct answer is D
The percentage error is \(\frac{error}{actual}\times \frac{100}{1}\%\\
=\frac{200-190}{200}\times \frac{100}{1}\\
=\frac{10}{200}\times \frac{100}{1}\% = 5\%\)
