Answer: 16.7%
Step-by-step explanation:
Inflation is defined as the increase in price of good and services.
Given last year cpi to be 120 and that of this year is 144, increase in cpi will be 144-120 which is 24cpi.
Year rate of inflation = final cpi - initial cpi/final cpi × 100%
Rate of inflation = 144-120/144×100%
Rate of inflation = 24/144×100%
Rate of inflation = 16.7%
Therefore the year rate of inflation is 16.7%
