Answer:

Step-by-step explanation:

It is given that  

Present value of car = 315600

Rate of depreciation (r) = 20%  

(i) We know that  

Value of car 2 years ago = A÷(1−r/100)  

n

 

Substituting the values  

=315600÷(1−20/100)  

2

 

By further calculation  

= 315600×5/4×5/4

= 493125

(ii) We know that  

Value of diamond after 3 years = 315600×(1−20/100)  

3

 

By further calculation  

= 315600×4/5×4/5×4/5

161587.20
