Challenge Problems
Push your limits with advanced challenges
Given that four scrapers yield a production of 500 bcm per hour and the cost per cubic meter is ₹50. Calculate the new cost per cubic meter if the number of scrapers is increased to six and output increases by 20%.
💡 Hint: Think of how the productivity increases impacts the overall cost.
If the hourly cost of operating a scraper is ₹4500 and a pusher is ₹5600, calculate the total operational cost if you are using 5 scrapers and 1 pusher for one hour.
💡 Hint: Break down each component of the operational cost for clarity.
