Manpreet bought a new car. The value of the car is Rs. 45000. If rate of depreciation is 10% perannum then what will be the value of the car after 2 years

Answer» \underline \bold{Solution:-}

Cost of CAR (P) = 45000rupees

Time = 2 YEARS

Rate of DEPRECIATION = 10 %

Amount

= P {(1 - \frac{rate}{100}) }^{time} \\
= 45000 {( 1-\frac{10}{100}) }^{2} \\ \\ = 45000 {( 1 - 0.1) }^{2} \\ \\ = 45000 \times {0.9}^{2} \\ \\ =36450

After 2 years it's cost will be 36450 rupees.
