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
