Question

From the data given below, construct the index number for the year 2016 on the base of 2011 by simple aggregative method:

Commodities	Unit	Price (In ₹)
		2011	2016
Wheat	quintal	200	250
Rice	quintal	300	400
Pulses	quintal	400	500
Milk	litre	2	3
Clothing	meter	4	5

Answer 1

Commodity	Price in 2011 (P0)	Price in 2016 (P1)
Wheat Rice Pulses Milk Clothing	200 300 400 2 4	250 400 500 3 5
	ΣP0 = 906	ΣP1 = 1158

$$\begin{gathered} P_{{01}_{}}=\frac{\Sigma P_1}{\Sigma P_0}\times 100 \\ \mathrm{or},P_{{01}_{}}=\frac{1158}{906}\times 100 \\ \Rightarrow P_{{01}_{}}=127.81 \end{gathered}$$
