It takes brothers John and Dan the same amount of time to clean the room they share, but John can mow the lawn faster than Dan. Which action would allow them to take advantage of their respective comparative advantages?

John mowing the lawn and Dan cleaning their room

John mowing the lawn and Dan cleaning the room.

Explanation:

The law of comparative advantage emphasizes on a country or individual to concentrate in what he/she has comparative advantage in doing. To benefit both John and Dan, since John has a comparative advantage in lawn mowing, he should concentrate on mowing the lawn while Dan concentrates on cleaning the room. This way, a lot of time and effort will be saved on both side.
