Answer:
Let's break this down step by step:
1. The man sold the computer for Rs 64,000.
2. The depreciation rate is 20% per annum.
3. To find the original price, we can set up an equation:
Selling Price = Original Price - (Original Price x Depreciation Rate x Number of Years)
Rs 64,000 = Rs 1,25,000 - (Rs 1,25,000 x 0.20 x Number of Years)
1. Simplify the equation:
Rs 64,000 = Rs 1,25,000 - Rs 25,000 x Number of Years
Rs 64,000 = Rs 1,00,000 - Rs 25,000 x Number of Years
1. Solve for Number of Years:
Number of Years = (Rs 1,00,000 - Rs 64,000) / Rs 25,000
Number of Years = Rs 36,000 / Rs 25,000
Number of Years = 1.44 years (approximately)
Since the depreciation rate is 20% per annum, we can assume the computer was used for approximately 1-2 years.
Step-by-step explanation:
Note: The calculation assumes a constant depreciation rate over the years. In reality, depreciation rates may vary, and this calculation serves as an estimate.
