Question

Construct the Index Number for 2011 with 2015 as base from the following prices of commodities by simple (Unweighted) aggregative method.

Commodities	:	A	B	C	D	E
Prices in ₹(2015)	:	50	40	10	5	2
Prices in ₹(2011)	:	80	60	20	10	6

[Index Number = 164.48]

Answer 1

Commodity	Prices in 2015 (p0)	Prices in 2011 (p1)
A B C D E	50 40 10 5 2	80 60 20 10 6
	∑ p0 = 107	∑ p1 = 176

$p_{01}=\frac{\mathrm{\Sigma }{p}_1}{\mathrm{\Sigma }{p}_0}\times 100=\frac{176}{107}=164.48$

Thus, price index is 164.48.
