A machine depreciate at 10% of it's value at the beginning of a year. ...
The problem of depreciation can be solved using the formula for the value of an asset after a certain number of years, taking into account its depreciation rate.

Understanding Depreciation
Depreciation is the reduction in the value of an asset over time. For this machine, it depreciates at a constant rate of 10% per year. The formula for the value of the machine after 'n' years can be expressed as:
  • Value after n years = Initial Cost × (1 - Depreciation Rate)n



Given Values
- Initial Cost = ₹23240
- Scrap Value = ₹9000
- Depreciation Rate = 10% or 0.10

Setting Up the Equation
To find out for how many years the machine was in use, we set up the equation:
  • Scrap Value = Initial Cost × (1 - 0.10)n
  • ₹9000 = ₹23240 × (0.90)n



Solving for n
1. Dividing both sides by ₹23240 gives:
  • (0.90)n = ₹9000 / ₹23240
  • (0.90)n ≈ 0.387


2. Taking the logarithm of both sides:
  • n × log(0.90) = log(0.387)
  • n = log(0.387) / log(0.90)


3. Calculating the values:
  • n ≈ 6.56


Thus, the machine was used for approximately 6.56 years, which we can round to 7 years for practical purposes.

Conclusion
The machine was effectively put to use for about 7 years before reaching its scrap value.
