Answer 1

Answer:

Group weight index number = 269.2

Step-by-step explanation:

GROUP      WEIGHT       INDEX NUMBER           WEIGHT * INDEX NUMBER

Food          35                425                                 14875

Cloth          15                 235                                 3525

Power         20               215                                   4300

Rent            8                  115                                     920

Misc            22                150                                  3300

                 100                1140                                 26920

Group weight index number  =  Weighted Index/ Total Weight

=  26920/100  

= 269.2

Group weight index number = 269.2

Simple Index Number = Total Index Number/ Total Items

= 1140/5

= 228

Answer 2

General Index Number = 269.20
