Challenge Problems

Push your limits with challenges.

Question 1

Consider a construction site with 3 machines where machine A is down for 15% of the project time, machine B for 20%, and machine C for 10%. If each machine has equivalent operating costs and downtime implications, how should costs be represented when calculating total downtime expenses?

💡 Hint: Factor in how these percentages interact to affect project efficiency.

Question 2

A company operates two excavators. When one is repaired, productivity drops by 30%, thereby leading to increased operational costs. If operational costs are $250,000 annually, estimate the increase in expenses due to downtime based on the productivity loss.

💡 Hint: Reflect on how productivity directly affects financials during operation.
