Given, the cost of machine = Rs 15625
Also, given that the machine depreciates by 20% every year.
Hence, its value after every year is 80% of the original cost i.e., \( \dfrac{4}{5}\) of the original cost.
\( 15625\times \dfrac{4}{5}\times \dfrac{4}{5}\times.......\times \dfrac{4}{5}\)
Therefore, the value at the end of 5 years =
= 5 × 1024 = 5120
Thus, the value of the machine at the end of 5 years will be Rs 5120.
