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%
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
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%
