Assertion: Marginal product of an input is equal to 0 at zero level of input employment. Reasoning: For any level of an input, the sum of marginal products of every preceeding unit of that input gives the total product. |
Both Assertion (A) and reasoning (R) are correct and R is the correct explanation of A. Both Assertion (A) and reasoning (R) are correct and but R is not the correct explanation of A. Assertion (A) is true but Reasoning (R) is not correct. Assertion (A) is not true but Reasoning (R) is correct. |
Assertion (A) is not true but Reasoning (R) is correct. |
The correct answer is Option 4: Assertion (A) is not true but Reasoning (R) is correct. Assertion: Marginal product of an input is equal to 0 at zero level of input employment. This is false because marginal product is not defined at zero level of input employment. Marginal Product measures the change in total product due to an additional unit of input. When input is zero, there is no “additional unit,” so MP cannot be said to be zero—it is simply not defined at that point. Reasoning: For any level of an input, the sum of marginal products of every preceeding unit of that input gives the total product. This is true. For any level of an input, the sum of marginal products of every preceeding unit of that input gives the total product. So total product is the sum of marginal products. |
