Question

Given the following table, find the Cost of living Index Number using Aggregate Expenditure Method by completing the activity.

Group	p0	q0	p1	p0q0	p1q0
A	23	4	25	`square`	100
B	15	5	20	75	`square`
C	5	9	8	`square`	72
D	12	5	18	60	`square`
E	8	6	13	`square`	78
Total	–	–	–	320	`square`

Therefore, Cost of Living Index using Aggregate Expenditure method is

CLI = `(sum"p"_1"q"_0)/(sum"p"_0"q"_0) xx square`

= `square/square xx 100`

= `square`

Answer 1

Group	p0	q0	p1	p0q0	p1q0
A	23	4	25	92	100
B	15	5	20	75	100
C	5	9	8	45	72
D	12	5	18	60	90
E	8	6	13	48	78
Total	–	–	–	320	440

Therefore, Cost of Living Index using Aggregate Expenditure method is

CLI = `(sum"p"_1"q"_0)/(sum"p"_0"q"_0) xx 100`

= `440/320 xx 100`

= 137.5
