Question

the value of car depreciates 20% every year if after 2 years the price of a car is rupees 420000 find the original price of the car

Answer 1

Answer:

The original price of the car is rupees 656250.

Step-by-step explanation:

Let the initial price of car be x.

It is given that if car depreciates 20% every year, then after two years the value of car is rupees 420000.

$x(1-\frac{20}{100})^2=420000$

$x(1-0.2)^2=420000$

$x(0.8)^2=420000$

$x(0.64)=420000$

$x=\frac{420000}{(0.64)}=656250$

Therefore the original price of the car is rupees 656250.
