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%
The correct answer is: D
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%
