Question

the present cost of a car is 382725. if its value has depreciated at the rate of 10% per annum ,what its cost 3 years ago . also find the total depreciation​

Answer 1

To solve this problem, let us know the formula for depreciation:

A = P × (1 - r/100)^n ,

where

• A = cost after n years
• P = present cost
• r = rate of depreciation

Now we proceed to solve the problem:

Given:

• Present cost of the car = Rs. 382725
• Rate of depreciation = 10 % p. a.
• Time = 3 years

To find:

• Cost of the car 3 years ago = ?
• Total depreciation = ?

Let the cost of the car before 3 years was Rs. P

Then, P × (1 - 10/100)^3 = 382725

or, P × (1 - 1/10)^3 = 382725

or, P × (9/10)^3 = 382725

or, P × 729/1000 = 382725

or, P = 382725 × 1000/729

or, P = 525000

Therefore 3 years ago, the cost of the car was Rs. 525000.

Hence total depreciation is

= cost (3 years ago) - present cost

= Rs. (525000 - 382725)

= Rs. 142275
