Question

The value of a machine depreciate at the rate of 5 percent per annum .It was purchased three years ago and if its present value is ₹965300 . For how much was it purchased ?​

Answer 1

Answer:

Answer

Present value of the machine P= 30,000, Rate of depreciation r=5%, Number of years n=3

The value of the machine after 'n' years =P(1−100r)n

∴ The value of the machine after three years =30000(1−1005)3

                                               =30000(10095)3

                                               =30000×10095×10095×10095

                                               =25721.25

The value of the machine after three years = 25,721.25

Answer 2

it will be:

present value = purchase (1-rate /100)^num. of years

from solving

it will be( 965300×8000)/(19×19×19)

=1125878
