Correct Answer: 2003 and 2004
Explanation:
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.

Correct Answer: 8.7
Explanation:
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.)
Correct Answer: 2002

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.
