At the end of each year the value of a certain machine has depreciated by
20% of its value at the beginning of that year. If its initial value was Rs 1250, find the
value at the end of 5 years.

• Rs. 409.6
  
  value at the end of 5 years = 1250*(0.8)^5 = Rs 409.6

• 
  1250 ---> 1000 ---> 800 ---> 640 ---> 512 --> 409.6
  
  Hence at the end of five years itz value should be 409.6
  
  (I have reduced the value every time by 20% in the above explaination)

• Rs. 409.60
  As the value of machine at the end of each year is depreciated by 20% of its value at the beginning of the year, so value at of machine at the end of a year is 80% of its value at the beginning of the year.
  Thus value at the end of 5 years = 1250*(0.8)^5 = Rs 409.60
