Question No 29:
Index Relatives: Fixed Base vs. Chain Base Methods
Fix base method = for commodities in which the basic nature is unchanged over time:
=(value in given year/value in base year)*100
Chain base method = for commodities where the basic nature changes over time:
=(this year's value/last year's value)*100
Index Relatives: Fixed Base vs. Chain Base Methods
Fix base method = for commodities in which the basic nature is unchanged over time:
=(value in given year/value in base year)*100
Chain base method = for commodities where the basic nature changes over time:
=(this year's value/last year's value)*100

Cima C03 Exam Question No 26
Question No 26:
Difference between General "And" Probability?
General Multiplication: conditional outcomes
P(A and B)=P(B)*P(A/B)
eg- if sales don't improve, there's a 70% chance we'll go under - P(A). There's a 20% chance that sales will improve - P(B). What's the probability of us going under? (PB does not depend on PA, but PA depends on PB) ∴ P(B)P(A/B)=0.80.7=0.56 - there's a 56% chance of us going under.
