Question

the index number of five commodities are 121 ,123 ,125,126,128, and the weights assigned to these are respectively 5,11,10,8,6.what us weighted average index n

​

Answer 1

Answer:

P = commodity

V = weight

PV = 121×5+ 123×11 + 125 × 10+ 126×8+ 128 × 6

= 4984

P = 40

weighted average = PV / V

index number

= 4984 / 40

= 124.6
