Question

The value of a mechine depreciates the rate of 10%every year . If it's present value is RUPEES81,000. Find the value of mechine 1)After 2 years 2)Two years ago​

Answer 1

Answer:

Step-by-step explanation:

For these type of questions we generally use formula of compound interest .So formula is

A= P(1-rate/100)^t

According to your problem

We have to find A So

P = 100000 Rate = 10 t = 2

So put values on formula

A = 100000(1-10/100)^2

Opening the brackets and solving the values ....

A = 100000*9/10*9/10

Cut the zeros and we left with

A = 1000*81

So finally the answer is......

A = 81000

Therefore ....81000 will be amount after two years
