Question

the cost of a machine is 25, 600 if the value of the machine depreciate at the rate of 12 1/2% per annum find the cost of the machine after 3 years​

Answer 1

Step-by-step explanation:

We know that

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.
