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

  1. During which of the given years increase in number of hotels over the previous year was highest?









  1. View Hint View Answer Discuss in Forum

    Increase in number of hotels over previous years = (number of hotels in previous year - number of hotels in current year).

    Correct Option: C

    Increase in number of hotels over previous years = (number of hotels in previous year - number of hotels in current year).
    Increase in number of hotels over previous years are as follows:
    In 2004, 440 - 410 = 30
    In 2005, 570 - 440 = 130
    In 2006, 740 - 570 = 170
    In 2008, 838 - 710 = 128
    Hence, in 2006, increase in number of hotels over 2005 was highest.


  1. What is the approximate percentage increase in to tourist hotels in 2008 over that in 2003?









  1. View Hint View Answer Discuss in Forum

    Increase in number of hotels = (number of hotels in 2008 - number of hotels in 2003 ).
    Required percentage of increase = (number of hotels in 2008 - number of hotels in 2003 ) x 100 / number of hotels in 2003

    Correct Option: B

    Increase in number of hotels = (number of hotels in 2008 - number of hotels in 2003 ).
    Required percentage of increase = (number of hotels in 2008 - number of hotels in 2003 ) x 100 / number of hotels in 2003
    Required percentage of increase = (838 - 410) x 100 /410 = 428 x 100 /410 = 100.4%
    Approximate 100%



  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


  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?









  1. View Hint View Answer Discuss in Forum

    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 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?









  1. View Hint View Answer Discuss in Forum

    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
