Step-by-step explanation:
A country has comparative advantage in production if it produces at a lower opportunity cost when compared with other countries.
Arbroc opportunity cost in the production of goat yoghurt = 20 / 60 = 0.333
Arbroc opportunity cost in the production of Apples = 60 / 20 = 3
Arbez opportunity cost in the production of goat yoghurt = 20 / 40 = 0.5
Arbez opportunity cost in the production of apples = 40 / 20 = 2
Arbroc has a lower opportunity cost in the production of goat yoghurt, therefore, the country has a comparative advantage in the production of goat yoghurt.
Arbez has a lower opportunity cost when compared with other in the production of Apples, therefore, the country has a comparative advantage in production of Apples.
