Which index number formula satisfies both time reversal and factor reversal tests?
A. Simple aggregative index
B. Paasche index
C. Laspeyres index
D. Fisher's ideal index
Answer: Option D
Solution (By JKSSB Mock Tests)
Fisher's ideal index, being the geometric mean of Laspeyres and Paasche indices, is the only common formula that satisfies both time reversal and factor reversal tests, ensuring mathematical consistency.
