Answer:
Rupees 2,00,000
Step-by-step explanation:
Present value of machine = rupees 1,60,000
let the value of machine last year be rupees x
∵ the value of machine depriciate by 20% every year,
∴ the present value of machine = x - 20% of x
=> 160000 = x -20/100*x
=>160000 = x - 2x/10
=>160000 = 8x/10
=>160000 / 8/10 = x
=>160000*10/8 = x
=>200000 = x
∴The value of machine last year was rupees 2,00,000
