From the following table calculate the Price Index for the year 2015, with base year 2011 :

150

The correct answer is Option (3) → 150

Price index for 2015 = $\frac{Price\,of\,commodities\,in\,2015}{Price\,of\,commodities\,in\,2011}×100$

Price index for A = $\frac{40}{32}×100=1.25×100=125$

Price index for B = $\frac{120}{80}×100=1.5×100=150$

Price index for C = $\frac{180}{100}×100=180$

Average Price index = $\frac{180+150+125}{3}≃150$
