The problem requires determining the useful life of a car using depreciation. Depreciation is calculated using the formula:
Depreciation Formula: \( \text{Annual Depreciation} = \frac{\text{Cost Price} - \text{Scrap Value}}{\text{Useful Life}} \)
Given data:
- Cost Price of the car = ₹8,50,000
- Scrap Value = ₹1,25,000
- Annual Depreciation = ₹1,45,000
Plugging in the values:
Equation: \( 1,45,000 = \frac{8,50,000 - 1,25,000}{\text{Useful Life}} \)
Simplifying the equation:
- Calculate the total depreciation: \( 8,50,000 - 1,25,000 = 7,25,000 \)
- Substitute back into the equation: \( 1,45,000 = \frac{7,25,000}{\text{Useful Life}} \)
- Solve for Useful Life: \( \text{Useful Life} = \frac{7,25,000}{1,45,000} \)
- Calculate: \( \text{Useful Life} = 5 \text{ years} \)
Therefore, the useful life of the car is 5 years.
