Question

The value of car depreciates by 15% if its present value is 450000 what was its value one year before

Answer 1

Answer:

Step-by-step explanation:

Let us suppose the value of the machine an year ago=x.  

It's 15% will be x*1%=x/15

If we analyze the question we can say that  

X-X/15= 450000

14X=450000 *15

X=675000/14

Therefore X= Rs. 4,82,142

hope it helps you !!!!

Answer 2

Present value of the car (P)

= Rs450000

depreciation(d)=15%

Let previous year car value = Rsx

P = x[(100-d)/100]

=>450000 = P[(100-15)/100]

=> 450000=P×(85/100)

=> (450000×100)/85 = P

=> 900000/17 = P

Therefore,

Last car price = P

= (900000)/17

Or

≈ Rs52941.18
