If the original price of as asset is 100 and rate of
depreciation is x, then 1st
year depreciation is x, residual value is (100x); 2nd year
depreciation is (x/100)*(100x) & residual value is (100x)*(1
x/100); 3rd year depreciation is (x/100)*(100x) *(1x/100) &
residual value (100x)*(1 x/100)^{2} and for nth year
depreciation is (x/100)(100x)(1x/100)^{n2 }and residual value is
(100x)*(1 x/100)^{n1}. The ratio of nth year depreciation & nth year residual value is 1/[100/x  1]
