Explanation:
Price of One Unit of Good= Total Spending / Total Quantity
In 2020,
They spend a total of $250 for 100 heads of cauliflower
Price of One Unit of Cauliflower = 250/100=$2.50 per unit
$100 for 50 bunches of broccolis,
Price of One Unit of Broccoli =100/50=$2 per unit
$250 for 500 carrots
Price of One Unit of carrot =250/500=$0.50 per unit
In 2021,
They spend a total of $210 for 60 heads of cauliflower
Price of One Unit of Cauliflower=210/60=$3.50 per unit
$180 for 90 bunches of broccolis,
Price of One Unit of Broccoli =180/90=$2 per unit
$270 for 450 carrots
Price of One Unit of carrot =270/450=$0.60 per unit

CPI Calculation:
Given: 2020 is the base year
So the CPI for 2020 is 100
(The CPI for base year is always 100 as it is used as benchmark in the calculation of CPI)
CPI for 2021:
Current year price = 210 + 180 + 270 = 660
Base year price = 250 + 100 + 250 = 600
CPI for 2021 = 110

Inflation rate = 10%
