Assuming the profit earned during the year 2001 as base (100), the profit made by the store during the year 2008 was:

Percentage of profit on the total in 2001 = Total profit in rupees x 100/ total sale in rupees.
Percentage of profit on the total in 2001 = 6.5 x 10000 x 100/3.5 x 100000 = 18.57
Percentage of profit on the total in 2002 = 11.5 x 10000 x 100/4.5 x 100000 = 25.56
Percentage of profit on the total in 2003 = 7.5 x 10000 x 100/8.5 x 100000 = 8.82
And Percentage of profit on the total in 2005 = 9.5 x 10000 x 100/ 8.5 x 100000 = 8.82
? Percentage of profit on the total sale in 2002 was the highest level.

Annual mean profit of the store (rupees in ten thousands)
= (6.5 + 11.5 + 7.5 + 4.5 + 9.5 + 11.5 + 10.0 + 8.5)/8 = 69.5/8 =8.7 (approx.)

Mean of annual increase in sale from 2003 to 2008 = (Sale in 2008 - sale in 2003 )/ (Difference in years)
Mean of annual increase in sale from 2003 to 2008 = 10.5 - 8.5/ 5 = 0.4

Rate of change in the amount of production in the year 2004 over the year 2003 = (Production in 2004 - Production in 2003 ) x 100/ Production in 2003
Rate of change in the amount of production in the year 2004 over the year 2003 = (35 - 30) x 100 / 30 = 5 x 100 / 30 = 16.67%
Similarly
Rate of change in the amount of production in the year 2006 over the year 2005 = (25 - 20) x 100 / 20 = 5 x 100/20 = 25%
Rate of change in the amount of production in the year 2007 over the year 2008 = (30 - 15) x 100 / 15 = 15 x 100/15= 100%
Rate of change in the amount of production in the year 2006 over the year 2007 = (25 - 15) x 100 / 15 = 10 x 100/15= 66.67%
Hence, it is clear that the rate of change in the amount of production during the consecutive years 2007 and 2008 is at the highest level.

Total production in 2005 and 2007 = 20 + 15 = 35 thousand tonnes. This total production is equal to the production in the year 2004.

Profit per cent during the year 2005 as compared to the previous year =(95 - 45) x 100/4.5 = 111.11%
Hence, profit in the year 2005 was more than 100% as compared to the previous year.

According to the graph, the two successive weeks vis., 30 June - 7 July shows highest increase of 180 - 142 = 38 in the number of persons killed.

According to the bar graph, two successive weeks, i.e. 7 July - 14 July shows maximum decline in the number of persons of killed in road accidents.

It is obvious from the bar graph that during the weeks beginning from 30 June. 14 July and 4 August, number of person killed remained less than 150.

According to the bar graph. number of person killed was more than 150 during the weeks beginning from 7 July, 21 July, 28 July and 11 August. Therefore number of such weeks = 4.
