Challenge Problems

Push your limits with challenges.

Question 1

A bulldozer has an ideal productivity of 120 loose cubic meters per hour on level terrain. If job efficiency is only 45 minutes, and soil density is modified at 1800 kg/m³ with average operator skill. Calculate the final productivity considering the necessary correction factors.

💡 Hint: Use the factors step by step to ensure accuracy in the productivity calculation.

Question 2

Explain how to derive the adjustment for unit cost if the total costs per hour increase by 10% due to higher wages and equipment wear, while output remains unchanged. Calculate and give the new unit cost if the previous unit cost was 30 rupees.

💡 Hint: Think about how costs and outputs are correlated in these calculations.
