A sales boy gave a change of N68 instead of N72. Calculate his percentage error
Answer Details
The sales boy gave a change of N68 instead of N72, which means he gave N4 less than he should have.
To find the percentage error, we use the formula:
Percentage Error = (Error / True Value) × 100%
In this case, the True Value is N72 and the Error is N4.
Substituting these values into the formula, we get:
Percentage Error = (4 / 72) × 100%
Percentage Error = 0.055555... × 100%
Percentage Error = 5.5555...%
Rounding off to the nearest whole number, we get:
Percentage Error ≈ 6%
Therefore, the sales boy's percentage error is approximately 6%.
The closest option to this answer is 5\(\frac{5}{9}\)%, so the answer would be:
- 5\(\frac{5}{9}\)%
