In this example, I couldn't understand the last point (which has been marked) sir. Can you explain how the sales below 30,000 units will yield higher profits in option (i) and sales above 30,000 units will yield higher profits in option (ii) by looking the graph sir?
You can see that at 30,000 units both lines intersect. i.e. profits are equal. After that point the line which is above will give higher profit.
Ok sir. Thank you!
