Results on Depreciation

We know that value of a machine depreciate with time, so it will decrease with the time. To calculate the value of machine after n years or before n years, we use these formula's

Let the present value of a machine be P. Suppose it depreciates at the rate of R% per annum.


\begin{aligned}
1. & \text{Population after n years =}P\left(1-\frac{R}{100}\right)^n \\

2.& \text{Population before n years =} \frac{P}{\left(1-\frac{R}{100}\right)^n} \\
\end{aligned}
