    As per given graph, we can see that,
    Sales in 2002 = 2 billion dollar
    Sales in 2007 = 6 billion dollar
    ∴ Required ratio = Sales in 2002 : Sales in 2007

    Correct Option: B

    As per given graph, we can see that,
    Sales in 2002 = 2 billion dollar
    Sales in 2007 = 6 billion dollar
    ∴ Required ratio = sales in 2002 : sales in 2007
    Required ratio = 2 : 6 = 1 : 3

    As per given line graph, we can see that the
    Sales in the year 2005 = 10 billion $
    Sales in the year 2004 = 4 billion $

    ∴ Percentage increase =Difference between both sales in 2005 and 2004 x 100
    total sales in 2004

    Correct Option: D

    As per given line graph, we can see that the
    Sales in the year 2005 = 10 billion $
    Sales in the year 2004 = 4 billion $

    ∴ Percentage increase =Difference between both sales in 2005 and 2004 x 100
    total sales in 2004

    Required percentage increase =10 - 4 x 100 = 150 %
    4



Direction: Study the following graph carefully and answer the questions given below it:

  1. If P is the percentage increase in tourist hotels from 2005 to 2006 and Q is the percentage increase in the tourist hotels from 2006 to 2008. Which of the following statements is true with respect to the relationship between P and Q?

    P = Number of hotels in 2005 to 2006 = (number of hotels in 2006 - number of hotels in 2005 ) x 100/ number of hotels in 2005

    Q = Number of hotels in 2006 to 2008 = (number of hotels in 2008 - number of hotels in 2006 ) x 100/ number of hotels in 2006

    Correct Option: C

    P = Number of hotels in 2005 to 2006 = (number of hotels in 2006 - number of hotels in 2005 ) x 100/ number of hotels in 2005
    Here, P = (740 - 570) x 100/570 = 29.8%
    Q = Number of hotels in 2006 to 2008 = (number of hotels in 2008 - number of hotels in 2006 ) x 100/ number of hotels in 2006
    and also, Q = (838 - 740) x 100/740 = 13.2%
    Hence, P > Q


  1. If percentage increase in number of hotels from 2007 to 2008 continued till 2009, how many new hotels would have come up in 2009?

    Number of hotels in 2007 to 2008 = (number of hotels in 2008 - number of hotels in 2007 ) x 100/ number of hotels in 2007

    Correct Option: D

    Number of hotels in 2007 to 2008 = (number of hotels in 2008 - number of hotels in 2007 ) x 100/ number of hotels in 2007
    Percentage increase in number of hotels from 2007 to 2088 = (838 - 710)x 100/710 = 128 x 100/710 = 18% approx.
    Since, required number of new hotels in 2009 = 838 x 18/100 = 150 approx.



  1. If in 2005 new hotels constructed were fewer by 10, what would have been the ratio between the new hotels constructed in 2004 and that constructed in 2005?

    See the graph and calculate the number of hotels.

    Correct Option: A

    Required ratio = (440 - 410) : (570 - 10 - 440) = 30 : 120 = 1 : 4
