Answer:
no
Explanation:
In order to achieve optimal employment level, the ratio of productivity between employees must be equal to the ratio between their wages, e.g. an employee who is 25% more productive, should earn 25% more.
In this case, the productive ratio is 15:20 or 3:4, while the wage ratio is 8:12 or 2:3. Since the wage ratio is lower than the productivity ratio (2:3 < 3:4), the two employees are not optimally employed.
