Challenge Problems
Push your limits with advanced challenges
Estimate the hourly productivity if the original expectation is 120 m³/hour, but correction factors for soil density (0.85), poor visibility (0.75) and operator skill (0.70) have to be applied.
💡 Hint: Multiply each correction factor by the initial productivity.
If a bulldozer's operational cost is 1600 rupees per hour, with a productivity of 40 bank m³/hour, calculate the unit cost per bank m³.
💡 Hint: This is a basic division of costs by productivity.
