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%

Explanation

The percentage error is \(\frac{error}{actual value}\times \frac{100}{1}\)%
= \(\frac{200-190}{200}\times \frac{100}{1}\)
= \(\frac{10}{200}\times \frac{100}{1}\)% = 5%
