The formula for a simple aggregative price index is:
P01=Σp1Σp0×100
Where:
Σp0 = sum of total prices in base year.
∑p1 = sum of total prices in current year.
P01 = index number of the current year
P01=∑(P1Q0P0Q0)×100 is the formula of:
(I) A rising price index implies a growing level of economic activity.
(II) Simple index number can be constructed only by the simple aggregative method.
Calculate the simple aggregative price index on the basis of the following data:
