    According to given bar graph , we have
    Total demand of the five companies = 3300 + 1200 + 3000 + 600 + 2500 = 10600
    Total production of the five companies = 2200 + 2700 + 1500 + 1800 + 1000 = 9200
    Number of given companies = 5

    Required difference =
    Total demand of the five companies
    -
    Total production of the five companies
    Number of given companiesNumber of given companies

    Correct Option: C

    According to given bar graph , we have
    Total demand of the five companies = 3300 + 1200 + 3000 + 600 + 2500 = 10600
    Total production of the five companies = 2200 + 2700 + 1500 + 1800 + 1000 = 9200
    Number of given companies = 5

    Required difference =
    Total demand of the five companies
    -
    Total production of the five companies

    From the given bar diagram , we see
    Number of companies having more demand than production ( In A, C and E companies ) = 3
    Number of companies having more production than demand ( In B and D companies ) = 2
    Required ratio = Number of companies having more demand than production : Number of companies having more production than demand

    Correct Option: D

    From the given bar diagram , we see
    Number of companies having more demand than production ( In A, C and E companies ) = 3
    Number of companies having more production than demand ( In B and D companies ) = 2
    Required ratio = Number of companies having more demand than production : Number of companies having more production than demand
    Required ratio = 3 : 2

    As per the given bar graph , we have
    The sales of table clock in 2010 = 22.3 lakhs
    The sales of table clock in 2005 = 9.5 lakhs
    Increase = 22.3 - 9.5 = 12.8

    Percentage increase in the sales of table clocks =
    Increase
    × 100
    The sales of table clock in 2005

    Correct Option: A

    As per the given bar graph , we have
    The sales of table clock in 2010 = 22.3 lakhs
    The sales of table clock in 2005 = 9.5 lakhs
    Increase = 22.3 - 9.5 = 12.8

    Percentage increase in the sales of table clocks =
    Increase
    × 100
    The sales of table clock in 2005

    Percentage increase in the sales of table clocks =
    12.8
    × 100 ≈ 135
