Explain inflation

The inflation rate in India is measured by the wholesale price index. The inflation rate has been increased to a greater percent after the independence. The average rate of inflation in 1950 was only 1.7%. But in the 1960’s it was 6.4%, and it reached 9% in the 1970s. It remained almost 4.7% between 2000-01 and 2011-12. Overall average WPI inflation from 1959-60 to 2010-11 is 6.8 percent (7.65 percent for 1970-71 to 2010-11), and CPI inflation from 1970-71 to 2010-11 is 8.08 percent. However, this average hides significant differences. Some of those key differences are: First, the period from 1994-95 to 2004-05 shows a consistent 10-year decreasing in inflation rates, unlike any other time in history. Second, although inflation has started rising after 2004-05, it still is not close to the pre-1994-95 phase.
