By computing the total physical output
Finding the total revenue
By computing marginal physical productivity
Marginal physical productivity multiplied by the value of the commodity i.e., price
Answer is Wrong!
Answer is Right!
The correct answer is D. Marginal physical productivity multiplied by the value of the commodity i.e., price.
Marginal physical productivity (MPP) is the additional output produced by adding one more unit of input. The value of the commodity is the price of the commodity. Therefore, the revenue marginal productivity is the MPP multiplied by the price of the commodity.
Option A is incorrect because it does not take into account the price of the commodity. Option B is incorrect because it does not take into account the MPP. Option C is incorrect because it does not take into account the price of the commodity or the MPP.
