Question

The value of a car depricates 15% every year. If the present value of the car is Rs 3,61,250 after two years What was the original price of the car?​

Answer 1

Answer:

Let the original price of car be x now, x(1-15/100)² ⇒ 361250 × (17/20)² = 361250×20/17×20/17 = 21250×20×20/17 = 1250×20×20 = 500000

So the original price of the car was ₹500000.

Answer 2

$\sf\red{Answer:-}$

Value of car depreciates by 15% every year

• let value of car be P

Car value after 1 year = (100-15)% of P

= 85%of P

• Car value after 2 year = 85% of 85% of P

• Car value after 3 year = 85%of 85% of 85% of P

• Depreciation in 3 years = P- 85% of 85%of 85%of P

= P- 0.85×0.85×0.85P

= P- 0.614P

= P (1-0.614)

=0.386P

So, %depreciation in 3years =0.386×100

=38.6%
