Question
The cost of a car depreciates at the rate of 20% every year. If its present worth is ₹ 315600, find the purchase value of the car, if it was purchased two years back.
Answer: Option A
:
A
Given that A =₹ 3,15,600 , r = 20 % ; n = 2 years.
Let P be the value of the car two years ago.
A=P(1−20100)2
315600=P(1−15)2
315600=P(4×45×5)
P=315600×5×54×4
P=₹4,93,125
∴Purchase value of the car=₹4,93,125
