Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A company has a defender with an initial cost of 20,00,000, annual operating costs of 1,00,000, and a salvage value of 5,00,000 after 8 years. They are considering a challenger with an initial cost of 25,00,000 with a 6,00,000 salvage value and operating costs of 80,000 annually. Calculate the equivalent annual cost for both and determine which is preferable.

💡 Hint: Use the uniform series factors for both EAC calculations based on time and costs.

Challenge 2 Hard

Determine the financial impacts if the defender's salvage value unexpectedly decreases to 3,00,000. Would this affect the decision to keep it or switch to the challenger?

💡 Hint: Look closely at how the changes to salvage affect the bottom line.
