the cost price of machine is 2,50,000.if the rate of depreciation is 10% per year find the depreciation in price of machine after two years.

Answers

Step-by-step explanation:

cost price= 250000

depreciation= 10%

time or years= 2

depreciation price = cost price× depreciation%

2,50,000×10%

2,50,000×10/100

25,000

then 2 years depreciation = 1 year depreciation price ×number of years

25,000× 2

50,000

therefore depreciation price of machine after 2 years is 50,000
