    From the given bar diagram , we see
    Total production of the companies A, B and C = 1500 + 1800 + 1000
    Number of companies A, B and C = 3
    Total production of the companies D and E = 2700 + 2200
    Number of companies D and E = 2
    Required ratio = Average production of the companies A, B and C : Average production of the companies D and E

    Correct Option: B

    From the given bar diagram , we see
    Total production of the companies A, B and C = 1500 + 1800 + 1000
    Number of companies A, B and C = 3
    Total production of the companies D and E = 2700 + 2200
    Number of companies D and E = 2
    Required ratio = Average production of the companies A, B and C : Average production of the companies D and E
    Required ratio
    Required ratio = 2 × 4300 : 4900 × 3 = 86 : 147


  1. What is the difference between average demand and average production of the companies taken together?

    On the basis of given graph in question ,
    Total demand of the companies = 3000 + 600 + 2500 + 1200 + 3300 = 10600
    Number of companies = 5

    ∴ Average demand =
    Total demand of the companies
    Number of companies

    ∴ Average demand =
    10600
    = 2120
    5

    Total production of the companies = 1500 + 1800 + 1000 + 2700 + 2200 = 9200
    ∴ Average production =
    Total production of the companies
    Number of companies

    Correct Option: C

    On the basis of given graph in question ,
    Total demand of the companies = 3000 + 600 + 2500 + 1200 + 3300 = 10600
    Number of companies = 5

    ∴ Average demand =
    Total demand of the companies
    Number of companies

    ∴ Average demand =
    10600
    = 2120
    5

    Total production of the companies = 1500 + 1800 + 1000 + 2700 + 2200 = 9200
    ∴ Average production =
    Total production of the companies
    Number of companies

    ∴ Average production =
    10600
    = 1840
    5

    Required difference = Average demand : Average production
    Required difference = 2120 – 1840 = 280

    According to given bar graph , we have
    The demand of company C = 2500 units
    The demand of company B = 600 units

    Required percentage =
    The demand of company B
    × 100
    The demand of company C

    Correct Option: C

    According to given bar graph , we have
    The demand of company C = 2500 units

    × 100
    The demand of company C

    Required percentage =
    600
    × 100 = 24%
    2500
