Fisher's ideal index for quantity is the geometric mean of:
A. Simple and weighted indices
B. Fixed base and chain base indices
C. Laspeyres and Paasche price indices
D. Laspeyres and Paasche quantity indices
Answer: Option D
Solution (By JKSSB Mock Tests)
Fisher's ideal quantity index = √(Laspeyres quantity index × Paasche quantity index), mirroring the price index formulation to satisfy consistency tests for quantity measurement.
