Which index number test checks if P₀₁ × P₁₂ × P₂₀ = 1?
A. Unit test
B. Time reversal test
C. Circular test
D. Factor reversal test
Answer: Option C
Solution (By JKSSB Mock Tests)
The circular test verifies consistency across three periods: the product of indices linking 0→1, 1→2, and 2→0 should equal 1 (or 100³ in percentage terms), ensuring transitivity in comparisons.
