Answer 2

We'll assume that the CPI is given for the END of the year.

Then 2014's rate is the change in price from 2013 in percent,

r = 180/125 - 1 = 36/25 - 1 = 11/25 = 44 %

Answer: choice c

----------

This is a pretty poor question. The questioner should clarify the exact dates of the given values of the CPI, and use the actual values. 44% is an alarming inflation rate, but fortunately a fictitious one here in the US. US inflation in 2014 was around 0.7% so the number the student was asked to compute was off by more than a factor of sixty.
