present value of a washing machine isRs 84000. If it depreciates at the rate of 2.5% per annum.Find the value of washing machine after 3 years. Also find by how much the value of washing machine gone down?​

Answer 1

Answer:

Final price = initial price(1+100rate)time

Here the final price = Rs. 8784, time =3 yrs, rate =−10%p.a.

The rate is negative since the price is depriciating.

Let the initial price = Rs. x.

∴x×(1−10010)3=8748

⇒x×109×109×109=8748

⇒x=8748×910×910×910= Rs. 12000

So, the price of the machine 3 years back = Rs. 12000.
