Given, Rate of depreciation = 20%

Value of machine today = 160000

-------------------------------------------------------------------------------------------------------------

Now, as the value is depreciating,

So before 1 year the value of machine was 100%

After 1 year that is today the value of machine has fallen by 20%

So value of machine today = 100 - 20 = 80%

Let the value of machine last year was x

Value of machine today is,

80% of x = 160000

80x/100 = 160000

80x = 16000000

x = 16000000/80

x = 200000

So, value of machine before 1 year was 200000.
