based on the information given below.
The retail prices of flowers, consumer expenditure on flowers and sales of flowers for the calendar year 2009, in Phoolgaon, a small town with a population of 70000, is summarized in table 3:
Total population = 70000
Average consumer expenditure on Roses and carnations = 47.4
Total expenditure on both carnations and roses = 47.4*70000
                                    = 3318000
Given total expenditure on roses = 1136916
So the total expenditure on carnations = 3318000 - 1136916
                              = 2181084
Similarly in the month of MarchÂ
Average consumer expenditure on Roses and carnations = 49.5
Total expenditure on both carnations and roses = 49.5 *70000
                                    = 3465000
Given total expenditure on roses = 1137915
So the total expenditure on carnations = 3465000Â - 1137915
                              = 2327085
Percentage increase in Expenditure = (2327085-2181084)/2181084
=6.69%
Hence C is the correct answer
