Direction: The bar graph as shows below gives information about the sale and profit details of a departmental store during the years from 2001 - 2008. Study the graph carefully and answer the questions asked here under.

  1. Annual mean profit of the store (rupees in ten thousand) is approximately:








  1. View Hint View Answer Discuss in Forum

    Annual mean profit of the store (rupees in ten thousands)
    = Add the annual income of every years / difference of the year

    Correct Option: C

    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.)

  1. Mean of annual increase in sale from 2003 to 2008 (rupees in lakhs) is:








  1. View Hint View Answer Discuss in Forum

    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

Direction: The following bar graph shows the producation of food grains in India during certain year. Study the graph carefully and answer the questions given below:

  1. Rate of change in quantity of production in which of the following two consecutive years is at the minimum level?

    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.

  1. Total food grain production in 2005 and 2007 is equal to the production during which of the following years?








  1. View Hint View Answer Discuss in Forum

    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. Percentage increase in the production of foodgrains in the year 2008 over the year 2007 is:








  1. View Hint View Answer Discuss in Forum

    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%
