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 2007Correct 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:
 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 2006Correct 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
 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.
 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
