Question

Answer 1

Answer:

16%

Step-by-step explanation:

$Error percent= \frac{wrong value-originalvalue}{originalvalue} *100\\=\frac{25-21}{25}*100 \\=\frac{4}{25} *100\\=16 percent$

Answer 2

Answer:

16%

Step-by-step explanation:

Formula for error Percentage = $\frac{difference}{correct value}$ ×100

Here Original Weight = 25Kg

Value of Mistaken Weight = 21Kg

Error = Difference = | Original Weight - Mistaken Weight | = | 25 - 21 | Kg

Therefore, Error = 4Kg

Putting values, Error Percentage = $\frac{4}{25}$ ×100 = 16%
