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