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.

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 2003Correct 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%

See the graph and calculate the number of hotels.
Correct Option: A
Required ratio = (440 - 410) : (570 - 10 - 440) = 30 : 120 = 1 : 4
- 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 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?
-
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 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
