Question

Suppose that a worker in Agland can produce either 10 units of organic grain or 2 units of incense per year, and a worker in Zenland can produce either 5 units of organic grain or 15 units of incense per year. There are 20 workers in Agland and 10 workers in Zenland. Currently the two countries do not trade. Agland produces and consumes 100 units of grain and 20 units of incense per year. Zenland produces and consumes 50 units of grain and no incense per year. If each country made the decision to specialize in producing the good in which it has a comparative advantage, then the combined yearly output of the two countries would increase by

A) 30 umits of grain and 10 units of incense. and 100 units of incense
B) 30 units of grain 30 units of grain and 150 units of incense.
C) 50 units of grain and 90 units of incense.
D) 50 units of grain and 130 units of incense
E) 50 units of grain and 130 units of incense.

Answer 1

D) or E) (are this the same?) 50 units of grain and 130 units of incense

Step-by-step explanation:

Agland has an advantage producing Organic grain, and Zealand producing Incense, So:

If Agland specialices in producing organic grain it would produce with 20 workers 200 units of grain a year.

If Zealand specialices in producing Incense, it would produce with 10 workers 150 units of incense a year.

This gives a Total combined output of 200 units of grain and 150 unit of incense a year.

Given that the total current output of the two countries is 150 units of grain and 20 units of incense it would increase in 50 units of grain and 130 units of incense.
