Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is the impact on production when using fewer scrapers than necessary?

💡 Hint: Think about the relationship between the number of machines and production flow.

Question 2

Easy

If a pusher costs ₹5600 per hour, how much would five scrapers cost?

💡 Hint: Remember to multiply the number of scrapers by their individual cost.

Challenge Problems

Push your limits with challenges.

Question 1

A construction site uses a combination of scrapers and pushers. If the costs for the machinery are increased by 10%, how will this impact the unit production cost calculations?

💡 Hint: Calculate the new hourly costs before recalculating the unit production cost.

Question 2

If the available scrapers at a site is cut down to three after a mechanical failure, how might this shift the operation and production rates?

💡 Hint: Consider the implications of fewer machines impacting throughput.
