बेरीज

उत्तर

Given: ∑p₀q₀ = 140, ∑p₀q₁ = 200, ∑p₁q₀ = 350, ∑p₁q₁ = 460

Laspeyre’s Price Index Number:

`P_01(L) = (sum p_1 q_0)/(sum p_0 q_0) xx 100`

= `350/140 xx 100`

= 250

Paasche’s Price Index Number:

`P_01(P) = (sum p_1 q_1)/(sum p_0 q_1) xx 100`

= `460/200 xx 100`

= 230

Dorbish-Bowley’s Price Index Number:

`P_01(D - B) = (P_01(L) + P_01(P))/2`

= `(250 + 230)/2`

= `480/2`

= 240

Marshall-Edgeworth’s Price Index Number:

`P_01(M - E) = (sum p_1 q_0 + sum p_1 q_1)/(sum p _0 q_0 + sum p_0 q_1) xx 100`

= `(350 + 460)/(140 + 200) xx 100`

= `810/340 xx 100`

= 238.24

Commodity	Price	Quantity	Price	Quantity
A	2	10	2	5
B	2	5	x	2

Solution: P₀₁(L) = P₀₁(P)

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

`(20 + 5x)/square xx 100 = square/14 xx 100`

Commodity	Price p₀	Quantity q₀	Price p₁	Quantity q₁
I	8	30	12	25
II	10	42	20	16

Solution:

Commodity	Base Year		Current Year		p₁q₀	p₀q₀	p₁q₁	p₀q₁
	p₀	q₀	p₁	q₁	p₁q₀	p₀q₀	p₁q₁	p₀q₁
I	8	30	12	25	360	240	300	200
II	10	42	20	16	840	420	320	160
Total					`bb(sump_1q_0=1200)`	`bb(sump_0q_0=660)`	`bb(sump_1q_1=620)`	`bb(sump_0q_1=360)`

Laspeyre's Price Index Number:

P₀₁(L) = `(sum"p"_1"q"_0)/(sum"p"_0"q"_0) xx 100 = square/660xx100`

∴ P₀₁(L) = `square`

Paasche 's Price Index Number:

P₀₁(P) = `(sum"p"_1"q"_1)/(sum"p"_0"q"_1) xx 100=(620)/(square) xx 100`

∴ P₀₁(P) = `square`
