Question:
Read the following statements - Assertion (A) and Reasoning (R):
Assertion: With the factor price given, initially the SMC falls, and then after a certain point, it rises.
Reasoning: According to the law of variable proportions, initially, the marginal product of a factor increases and after a certain point, it decreases. This means, initially, to produce every extra unit of output, the requirement of the factor becomes less and less, and then after a certain point, it becomes greater and greater.
From the given alternatives choose the correct one:
Options:
Both Assertion (A) and Reasoning (R) are true and Reasoning (R) is the correct explanation of Assertion (A).
Both Assertion (A) and Reasoning (R) are true and Reasoning (R) is not the correct explanation of Assertion (A).
Assertion (A) is true but Reasoning (R) is false.
Assertion (A) is false but Reasoning (R) is true.
Correct Answer:
Both Assertion (A) and Reasoning (R) are true and Reasoning (R) is the correct explanation of Assertion (A).
Explanation:
As the law of variable proportions states: initially, the marginal product of a factor increases and after a certain point, it decreases. This means, initially, to produce every extra unit of output, the requirement of the factor becomes less and less, and then after a certain point, it becomes greater and greater. With the factor price given, initially the SMC falls, and then after a certain point, it rises.
