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:
Compared to January, the price of carnations in December
Solution
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
Sales of carnations in January = 13848 dozens
Price of carnation per dozen in January =2181084/13848
= 157.5
Similarly In December
Average consumer expenditure on Roses and carnations = 56.4
Total expenditure on both carnations and roses = 56.4*70000
= 3948000
Given total expenditure on roses = 977688
So the total expenditure on carnations = 3948000 - 977688
= 2970312
Sales of carnations = 18859 dozens
Price of carnation per dozen in January =2970312/18859
= 157.5
Therefore the price did not change
Hence E is the correct answer
