The bar graph as shown below gives information about the sales and profit details of a departmental store during the years from 20012008. Study the graph carefully and answer the questions asked here under.
Sales: (Rs. in Lakhs)
Profit: (Rs. in Ten thousands)
Solution
Increase in sales (rupees in lakhs) from :
2003 - 2004 = (7.5 - 8.5) = -1
2004 - 2005 = (5.5 - 7.5) = -2
2005 - 2006 = (8.5 - 5.5) = 3
2006 - 2007 = (8.5 - 8.5) = 0
2007 - 2008 = (10.5 - 8.5) = 2
Sum = (-1) + (-2) + (3) + (0) + (2) = 2
$$\therefore$$ Required mean = $$\frac{2}{5} = 0.4$$
