Let cost of printing machine at end of year 2001 = x
A printing machine depreciates in value by 8% every year
So, Cost of printing machine at end of year 2002 = 0.92*x
Cost of printing machine at end of year 2002 is 18400
0.92x=18400
x=20000
cost of printing machine at end of year 2001 is Rs 20,000
Cost of printing machine at end of year 2003 = 0.92*0.92*x=0.92*18400= Rs 16928
