Answer:
3% inflation rise. No correct cpi option
Explanation:
Consumer Price Index(CPI) is calculated by the Bureau of Economic Analysis and Statistics of a country monthly and annually. 
Consumer Price Index(CPI) is used for measuring the changes in the price level of consumer goods and services purchased by households.
Calculating the consumer price index; price in 1964= $1.25, today price= $5.0.
Therefore, consumer price index= Price in today- price in 1964÷ price in 1964,.
Consumer Price index(CPI)= $(5-1.25)/1.25 = 3.75/1.25 = 3 Percent price inflation rise.
For the first cpi; 112-80/80= 0.4 percent( not equal to the 3 Percent inflation rise).
For the second cpi: 141.6-60/60= 1.36 Percent inflation rise(not equal to the 3 Percent inflation rise).
For the third CPI: 126.4-75/75 =0.68 percent inflation rise[not equal to the 3 Percent inflation rise].
For the third CPI: 108.5-90/90=0.21 percent inflation rise(not equal to 3 Percent inflation rise)
Therefore, none of the options are right.
