Answer 2

The value of car in 2010 is Rs.120000

Step-by-step explanation:

Let the value of car in 2010 be x

We are given that Every year the value of a car depreciates by 15% of its value

So, Value of car in 2011 =$x- 15\%x= x-0.15x=0.85x$

Value of car in 2012 = $0.85x-15\%(0.85x)=0.85x-0.15(0.85x)=0.7225x$

We are given that the value of car in 2012 is Rs. 86700

So, $0.7225x=86700$

$x=\frac{86700}{0.7225}$

x=120000

Hence The value of car in 2010 is Rs.120000
