    On the basis of given graph in question ,
    Accidents in the month of February = 19
    Accidents in the month of January = 25
    Decrease in accidents = 25 - 19 = 6

    Required percent = Decrease in accidents × 100
    Accidents in the month of January

    Correct Option: B

    On the basis of given graph in question ,
    Accidents in the month of February = 19
    Accidents in the month of January = 25

    Required percent = Decrease in accidents × 100
    Accidents in the month of January

    Required percent =
    6
    × 100 = 24%
    25

    As per the given bar graph ,
    Total accidents in the city = 25 + 19 + 30 + 43 + 35 + 27 = 179
    Accidents in April = 43

    ∴ Required percent =
    Accidents in April
    × 100
    Total accidents in the city

    Correct Option: D

    As per the given bar graph ,
    Total accidents in the city = 25 + 19 + 30 + 43 + 35 + 27 = 179
    Accidents in April = 43

    ∴ Required percent =
    Accidents in April
    × 100
    Total accidents in the city

    ∴ Required percent =

    According to given bar graph , we have
    The total expenditure of the company = $ 20 millions, Percent expenditure on transport = 12.5%
    Percent expenditure on salary = 20%
    Ratio of expenses on transport and salary = 12.5 : 20

    Correct Option: C

    According to given bar graph , we have
    The total expenditure of the company = $ 20 millions, Percent expenditure on transport = 12.5%
    Percent expenditure on salary = 20%
    Ratio of expenses on transport and salary = 12.5 : 20
    Required Ratio = 125 : 200 = 5 : 8


  1. The ratio of the total expenditure on infrastructure and transport to the total expenditure on taxes and interest on loans is :

    From the given bar diagram , we see
    The total expenditure on infrastructure and transport = 20 + 12.5 = 32.5
    The total expenditure on taxes and interest on loans = 10 + 17.5 = 27.5
    Required ratio = The total expenditure on infrastructure and transport : The total expenditure on taxes and interest on loans

    Correct Option: D

    From the given bar diagram , we see
    The total expenditure on infrastructure and transport = 20 + 12.5 = 32.5
    The total expenditure on taxes and interest on loans = 10 + 17.5 = 27.5
    Required ratio = The total expenditure on infrastructure and transport : The total expenditure on taxes and interest on loans
    ∴ Required ratio = 32.5 : 27.5 = 13 : 11



  1. If the interest on loans amounted to $ 2.45 millions, then the total amount of expenditure on advertisement, taxes and research and development is :

    According to given bar graph , we have
    Given , The interest on loans = $ 2.45 millions
    Percentage expenditure on interest on loans = 17.5%
    Percentage expenditure on advertisement, tax and research and development = 15 + 10 + 5 = 30%
    ∵ 17.5% ≡ $ 2.45 million

    Correct Option: B

    According to given bar graph , we have
    Given , The interest on loans = $ 2.45 millions
    Percentage expenditure on interest on loans = 17.5%
    Percentage expenditure on advertisement, tax and research and development = 15 + 10 + 5 = 30%
    ∵ 17.5% ≡ $ 2.45 million

    ∴ 30% ≡ $ 2.45× 30 million
    17.5

    Required answer = $ 4.2 million
