In a world with only two countries, if Japan reduces the value of the yen by 20% and West Germany lowers the mark's value by 15%, what is the outcome for the yen relative to the mark?
Explanation
Since Japan devalues the yen by a larger percentage (20%) than West Germany devalues the mark (15%), the yen loses more value relative to the mark. Therefore, the yen depreciates against the mark.
