Solution

The problem is about depreciation, which is a decrease in the value of an asset over time. In this case, the value of the article decreases by 10% each year.

Here are the steps to solve the problem:

  1. We know that the present value of the article is Rs. 729.

  2. We need to find the value of the article 3 years ago. This means we need to reverse the depreciation process.

  3. Since the value decreases by 10% each year, it means that each year the value is 90% (100% - 10%) of the previous year.

  4. To find the value 3 years ago, we need to divide the present value by 0.9 (which is 90% expressed as a decimal) three times.

  5. So, the calculations would be as follows:

    First year: 729 / 0.9 = Rs. 810 Second year: 810 / 0.9 = Rs. 900 Third year: 900 / 0.9 = Rs. 1000

So, the value of the article 3 years ago was Rs. 1000.
