Challenge Problems

Push your limits with challenges.

Question 1

A machine starts with a cost of 50,00,000 and has a cumulative maintenance cost of 5,50,000 after 5 years. If its value depreciates to 25,00,000, what is the total cost over the 5 years?

💡 Hint: Combine all costs and subtract any revenue generated.

Question 2

You have data showing that a machine incurs 1,00,000 in downtime costs due to breakdowns in year six. If maintenance costs increase by 10% annually, what would the total cost be in year six including downtime?

💡 Hint: Calculate the new maintenance cost first, then add downtime costs.
