    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%

    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.

    Required ratio = (number of units manufactured in the year 2006 - number of units sold in the year 2006)/ (number of units manufactured in the year 2007 - number of units sold in the year 2007)

    Correct Option: B

    Required ratio = (number of units manufactured in the year 2006 - number of units sold in the year 2006)/ (number of units manufactured in the year 2007 - number of units sold in the year 2007)
    Required ratio = (5.5 - 5) / (5 - 3) = 0.5 / 2 = 1 / 4 = 1 : 4

    Required percentage of increase = (number of units sold in the year 2008 - number of units sold in the year 2007) x 100 / number of units sold in the year 2007

    Correct Option: D

    Required percentage of increase = (number of units sold in the year 2008 - number of units sold in the year 2007) x 100 / number of units sold in the year 2007
    Required percentage of increase = (6.5 - 3) x 100/3 = 3.5 x 100/3 = 117%

    Average number of units sold = ( Units sold in 2004 + Units sold in 2005 + Units sold in 2006 + Units sold in 2007 + Units sold in 2008 ) / 5

    Correct Option: B

    Average number of units sold = ( Units sold in 2004 + Units sold in 2005 + Units sold in 2006 + Units sold in 2007 + Units sold in 2008 ) / 5
    Average number of units sold = (3.5 + 4 + 5 + 3 + 6.5)/5 = 22/5 = 4.4 crores
