Answer:
The correct answer is option A.
Step-by-step explanation:
Freedonia and Sylvania both produce corn and wheat.
Freedonia can produce either 6 units of corn or 2 units of wheat per year.
A worker in Sylvania can produce either 2 units of corn or 6 units of wheat per year.
Each nation has 10 workers.
If Freedonia employs all its workers to produce corn and Sylvania uses all its workers to produce wheat both will be able to produce 60 units of corn and 60 units of wheat respectively.
They exchange 30 units of corn for 30 units of wheat.
Corn left with Freedonia
= 60 - 30 = 30 units
Wheat gained in exchange by Freedonia is 30 units.
Similarly, wheat left with Sylvania after the exchange
= 60 - 30 = 30 units
Corn gained in exchange by Sylvania is 30 units.
This means that both will now be able to consume 30 units of corn and 30 units of wheat.
