Assertion (A): Fisher's ideal index satisfies both time reversal and factor reversal tests. Reason (R): Fisher's index is the geometric mean of Laspeyres and Paasche indices. Choose the correct option: MCQ with Answer and Explanation
Assertion (A): Fisher's ideal index satisfies both time reversal and factor reversal tests. Reason (R): Fisher's index is the geometric mean of Laspeyres and Paasche indices. Choose the correct option:
A. A is false, R is true
B. A is true, R is false
C. Both A and R are true, and R is the correct explanation of A
D. Both A and R are true, but R is not the correct explanation of A
Answer: Option C
Solution (By JKSSB Mock Tests)
Fisher's index indeed satisfies both tests, and the formula (geometric mean) is the reason it meets these tests.
