  Well, there are a lot assumptions to be made and several variables to be considered, such as job scope and complexity, efficiency of workers, cooperativeness, law of diminishing marginal returns etc. So without the input of these parameters, it would be impossible to give any answer with any significant degree of accuracy and reliability.
