Question

The present price of a scooter is rs 7290. If it's value decreases every year's by 10%,then find its value before 3 years

Answer 1

Let the cost of the scooter before 3 years was x.

Given that amount = 7290 rupees, r = 10%, n = 3 years.

We know that A = P(1 - r/100)^n

                        7290 = x(1 - 10/100)^3

                       7290 = x(9/10)^3

                       7290 = x * (729/1000)

                       7290 = 729x/1000

                       7290 * 1000 = 729x

                       7290000 = 729x

                       7290000/729 = x

                       10000 = x.


Therefore the value of the scooter before 3 years ago = 10000 rupees.


Hope this helps!
