An inspector rejects 0.08% of the meters as defective. How many will he examine to reject 2?
Answer
Answer (as printed):
Explanation
Let the number of meters to be examined be $x$. Then, $0.08\%$ of $x=2 \Leftrightarrow \left(\frac{8}{100}\times\frac{1}{100}\times x\right)=2 \Leftrightarrow x=\left(\frac{2\times 100\times 100}{8}\right)=2500$.
