Percentage and Depreciation
The value of a computer depreciates by 10% annually. If the present value of the computer is Rs. 100,000, what will be its value after two years?
Explanation and memory cue
The computer depreciates by 10% annually, so after one year its value is 90% of 100,000 = 90,000. After the second year, it is 90% of 90,000 = 81,000. Therefore, the value after two years is Rs. 81,000.
