Question 7

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 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.
