  1. Percentage increase in the production of foodgrains in the year 2008 over the year 2007 is:
    1. 15%
    2. 30%
    3. 50%
    4. 100%

    Percentage increase in food grain production = (30 - 15 )/15 x 100

    Correct Option: D

    Percentage increase in food grain production = (30 - 15 )/15 x 100 = 100%

    Total production in 2005 and 2007 = 20 + 15 = 35 thousand tonnes.

    Correct Option: B

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

  1. Rate of change in quantity of production in which of the following two consecutive years is at the minimum level?
    1. 2003 and 2004
    2. 2005 and 2006
    3. 2007 and 2008
    4. 2006 and 2007

    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
    Similarly
    Rate of change in the amount of production in the year 2006 over the year 2005 = (Production in 2006 - Production in 2005 ) x 100/ Production in 2005

    Correct Option: A

    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.

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

    Correct Option: D

    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
