Answer B
The base value is always 100
The new price for food 110 Acco 100 and clothing 95
Total weights is 10
For food 5 /10 * 110 = 55
Acco 3 / 10 * 100 = 30
clothing 2 / 10 * 95= 19
Get the total which is 104
It has increased by 4 %
omg i was just about to ask u questions on calculating the weights.....so is this basically the overall formula to calculate the cpi?
