<h2>Answer:</h2><h2>The rate of depreciation of the car is 14%</h2>
Step-by-step explanation:
The price of car purchased 5 years ago = 15000
The price of car sold = 7000
By compound depreciation,
... (1)
where Pn = 7000
P = 15000
R = rate of interest to be calculated
T = 5 ( number of years)
substituting the values in equation (1), we get
0.858 is rounded off as 0.86
R/100 = 0.14
By simplifying the above equation, we get
Rate of depreciation = 14%
