Question

Find the Value Index Number using Simple Aggregate Method in the following example.

Commodity	Base Year		Current Year
	Price	Quantity	Price	Quantity
A	50	22	70	14
B	70	16	90	22
C	60	18	105	14
D	120	12	140	15
E	100	22	155	28

Answer 1

Commodity	Base year		Current year		p0q0	p1q1
	p0	q0	p1	q1
A	50	22	70	14	1100	980
B	70	16	90	22	1120	1980
C	60	18	105	14	1080	1470
D	120	12	140	15	1440	2100
E	100	22	155	28	2200	4340
Total	-	-	-	-	6940	10870

From the table, `sum "p"_0"q"_0 = 6940, sum"p"_1"q"_1 = 10870`

Value Index Number (V₀₁) = `(sum"p"_1"q"_1)/(sum "p"_0"q"_0) xx 100`

`= 10870/6940 xx 100`

= 156.63
