Official Explanation
(D) The smallest change in 2010 was approximately –0.1 in June 2010. The greatest change in 2011 was 0.7 in March 2011. The difference is 0.7 – (–0.1) = 0.8.
(B) In the second half of 2011, increases become smaller and by October, the CPI declines. The longest period of slowing change in the CPI was the second half of 2011, a period of six months beginning in August 2011.
chetan2u Sajjad1994I didn't get the explanation. Please help me out here:
Greatest change in CPI in 2011 = greatest slope, which seems to be in May-11 to June-11
And least change in 2010 = least slope = 0 from Nov-10 to dec-10
When it says ''greatest/least change'', we should be taking absolute values of the changes, right?
