Q. The value of a machine was reduced by 36%36\% within 22 years. What is the rate of depreciation per year?\newlineA. 6%6\%\newlineB. 18%18\%\newlineC. 20%20\%\newlineD. 36%36\%
  1. Calculate Yearly Rate: First, we know the machine's value decreased by 36%36\% over 22 years. To find the yearly rate, we divide the total percentage by the number of years.\newlineSo, 36%÷236\% \div 2 years = 18%18\% per year.
  2. Verify Yearly Rate: Now, let's check if the answer makes sense. If the machine loses 18%18\% of its value each year, then over 22 years, it would lose 18%+18%=36%18\% + 18\% = 36\%, which matches the given information.
