Question

Solve the following problem :

Find the Quantity Index Number using Simple Aggregate Method.

Commodity	Base year quantity	Current year quantity
A	100	130
B	170	200
C	210	250
D	90	110
E	50	150

Answer 1

Commodity	Base Year Quantity q0	Current Year Quantity q1
A	100	130
B	170	200
C	210	250
D	90	110
E	50	150
Total	620	840

From the table, `sum"q"_0 = 620, sum"q"_1 = 840`

Quantity Index Number (Q₀₁) = `(sum"q"_1)/(sum"q"_0) xx 100`

= `(840)/(620) xx 100`

= 135.48
