The Laspeyres quantity index uses which price weights?
Correct Answer: Option C
Explanation:
Laspeyres quantity index = Σ(q₁p₀)/Σ(q₀p₀) × 100, using base period prices (p₀) as weights to measure quantity changes holding prices constant at base levels.

General Fertility Rate (GFR) improves upon CBR by:
Correct Answer: Option D
Explanation:
GFR = (Live births / Women aged 15-49) × 1,000, focusing on the biologically relevant population for childbearing, making it a more refined fertility measure than CBR.

If P(A)=0.4, P(A∪B)=0.7, then the probability of B will be maximum when A and B are:
Correct Answer: Option B
Explanation:
P(A∪B)=P(A)+P(B)-P(A∩B). To maximize P(B) given P(A∪B)=0.7 and P(A)=0.4, set P(A∩B)=P(A)=0.4 (i.e., A⊂B). Then 0.7=0.4+P(B)-0.4 => P(B)=0.7 max.
