THE GRADES OF THE FACTORS OF PRODUCTION 131 



$70 on "C" land, which grade of land has the greater economic 

 efficiency? How much greater than the other? 



4. With given land and given equipment, farmer "A" produced 

 $80 worth of product; while farmer "B" could produce $110 worth 

 of product; which farmer has the greater economic efficiency? 

 How much greater? 



5. If a given amount of labor and equipment may be employed 

 profitably upon 100 acres of "N" land, or upon 120 acres of "M" 

 land, with a product of $1200 on the "N" land or a product of $1400 

 on the "M" land, which land has the greater capacity? How much 

 greater? Which has the greater efficiency? How much greater? 



6. If on the same farm cow No. 8 is kept and milked at an annual 

 cost of $45, while cow No. 9 is kept and milked at a cost of $60, and 

 cow No. 8 yields a product worth $54, while cow No. 9 yields a prod- 

 uct worth $72, which cow has the greater capacity? Which the 

 greater efficiency ? How much greater? 



7. Plow "A" requires 2 horses and one man and will plow 2 acres a 

 day. Plow " B " requires four horses and one man and will plow 3^ 

 acres a day. Compare the capacity and the efficiency of these plows 

 in terms of men and of horses. 



8. Workman "A" can pitch grain for 3 wagons in threshing, while 

 workman "B" can keep but two wagons going, and each of "AV 

 three wagons hauls 30 per cent more grain in a day ; but in harvest- 

 ing grain, "B" was able to drive five horses to an eight-foot binder, 

 while "A" was unable to drive more than a three-horse team to a 

 six-foot cut binder, and while "B" cut 15 acres of grain "A" cut 

 only 10 acres per day. Explain where each has the greater capacity 

 and where each has the greater efficiency.
