Solution
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
