 Govind said: (Jan 30, 2012) Add up all the 2001+2002 sales turnover carefully, and all the 2002+2003 values. Than find the change percentage thereafter you will get the answer not accurately 14.68%.

Mind it, during summation of the sales, all the sale are not exactly of round fig. i.e. it may contain 810, 840, 960 like that. Thank you. :).

 Chirayu said: (Sep 16, 2012) {(4750-4050)*100}/4750 = 14.68

 Pradeep said: (Apr 26, 2014) Like other bar charts, value should be given on the top of lines to calculate. Approximately, everyone has given the right calculation: 4750-4050 = 700. (700/4750)*100 = 14.73% near to 14.68%. Option (B).

 Sharmila said: (Jul 29, 2019) Denominator value is the base value. Base value is the one with which we compare the growth. Here, in this case, the value has been changed from the year 2001-02 to 2002 -03. So, 2001-02 total is taken as the base value.
