Question

Calculate a Quantity Index number of g the given data.

Commodities	Quantity in 2015 (base year) q0	Quantity in 2016 (Current year) q1
A	50	80
B	70	100
C	80	120

Answer 1

Commodities	Quantity in 2015 (base year) q0	Quantity in 2016 (Current year) q1
A	50	80
B	70	100
C	80	120
	Σq0 = 200	Σq1 = 300

where, Σq₀ = Sum total of all the commodities of the base year.

Σq₁ Sum total of all the commodities of the current year.

Quantity Index Number Q₀₁ =  \(\cfrac{Σq_1}{Σq_0} \times 100\)

\(= \cfrac{300}{200}\times 100\)

= 150

Hence, Q₀₁ = 150
