Question

The value of machine depreciates at the rate of 10 per cent per annum. It was purchased 3 years ago. If it's present value is rs 291600, for how much was it purchased?

Answer 1

Answer:

Let the Purchased price= 100X

After 1 year.. Price will = 100X -10% of 100x

= 90x.

After 2 years. Price will=90x-10% of 90x

= 81x

after 3 years.. price will= 81x-10% of 81x

=72.9x -------------------(i)

But value after 3 years is 291600 --------------------(ii)

by equation (i) and (ii)

72.9x= 291600

x = 4000

So Purchased price= 4000×100

=400000Rs
