A boy estimated his transport fare for a journey as N190 instead of N200. Find the percentage error in his estimate
Answer Details
The error in the boy's estimate is the difference between what he estimated and the actual cost of the journey, which is N200 - N190 = N10.
To find the percentage error, we divide the error by the actual cost and then multiply by 100%.
Percentage error = (error / actual cost) x 100%
= (10 / 200) x 100%
= 5%
Therefore, the percentage error in the boy's estimate is 5%. Option (d) is the correct answer.
