Index number sum no. 2

Dear Student,
 

Commodity	Prices in 1982 (P0)	Prices in 1990 (P1)
Rice	30*20 = 600	30*20 = 600
Pulse	35.50*6 = 213	35.50*6 = 213
Potato	12.50*4 = 50	10*4 = 40
Oil	90*3.5 = 315	100*3.5 = 350
Salt	8*1.5 = 12	10*1.5 = 15

                    ΣP₀ = 1190               ΣP₁ = 1218

P₀₁ = $\frac{\Sigma P_1}{ \Sigma P_0} *100$
       = $\frac{1218}{1190} * 100$
⇒ P₀₁ = 102.35
