Diminishing marginal returns occur when the marginal product of an additional worker is less than the marginal product of the previous worker. In this case, the marginal product of the fourth worker is only 25, compared to the marginal products of the first three workers (50, 75, and 80). This indicates that the addition of the fourth worker is where diminishing marginal returns start to set in.
