Car value then 8000 then total depreciating valu is:

[tex]\begin{gathered} \text{Total depreciating =New price-old price} \\ =20000-8000 \\ =12000 \end{gathered}[/tex]

If one year depreciating is 4000 so then decpreciating amount is 12000

[tex]\begin{gathered} \text{Year}=\frac{12000}{4000} \\ \text{year}=3 \end{gathered}[/tex]

After 3 year car value is 8000.
