Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given that you have 4 scrapers producing 500 bcm/hr and you decide to add another which increases the total to 650 bcm/hr, calculate the increase in overall productivity per scraper.

💡 Hint: Calculate the difference in productivity when adding the additional scraper.

Challenge 2 Hard

If using scrapers increases costs by ₹500 but the productivity raises by 100 bcm/hr, is it worth it based on production cost?

💡 Hint: Consider the relationship between costs and efficiencies to make a judgment.
