Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a machine with a purchase price of ₹50,00,000, a salvage value of ₹5,00,000, inflation of 4% annually, and a depreciation rate of 20%, calculate when the optimal replacement year would be for minimal costs over a 5-year period.

💡 Hint: Break down the calculations year by year for clarity.

Challenge 2 Hard

Create a comprehensive report analyzing three different machines with differing economic lives, costs, and salvage values to determine which should be replaced first, using cumulative cost analysis.

💡 Hint: Include all associated costs and evaluate them relative to their age.
