B:
if the base year bundle has 10 liter milk, 3 Dozen eggs, 2 packets of tea then
find the laspayers index by assuming June 2018 as the base year June 2020 as
the current year.
If
Milk
= 10 liter
Eggs = 3 Dozen
Tea = 2 packet
Multiply
the bundle with nominal price June-2018:
Milk
10*85=850
Eggs 3*83.13=249.39
Tea 2*205.26=410.52
Total cost =850+249.39+410.52
=1509.91
Multiply
the bundle with current nominal price of June-2020:
Milk
10*97.50=975.00
Eggs
3*115.63=346.89
Tea
2*242.10=484.20
Total
cost =975+346.89+484.20
=1806.09
The
Laspayres index will be:
By
divide current price with base price
=1806.09/1509.91
=1.196Answer
