The value of a machine depreciates at the rate of 10% per annum. What will be its value 2 years hence, if the present value is Rs 100000? Also, find the total depreciation during this period.
Given,
Present value of machine = Rs.100000
Rate of depreciation = 10% per annum
So,
Value of machine after 2 years = 
Total depreciation during this period = Rs.(100000 – 8100) = Rs.19000
