Question

A number $5.78\times {10}^3$ is wrongly written as $5.87\times {10}^3$. Find the percentage error.

• A. $1.56\%$
• B. $1.86\%$
• C. $1.76\%$
• D. $1.36\%$

Answer 1

The correct option is A $1.56\%$

Percentage error $=\frac{5.87\times {10}^3-5.78\times {10}^3}{5.78\times {10}^3}\times 100\%$ $=\frac{0.09}{5.78}\times 100\%$ $=1.56\%$
