    From the given bar diagram , we see
    Number of the month having more demand than production i.e.( January , March and May ) = 3
    Number of the month having more production than demand i.e. ( February , April ) = 2
    Required ratio = Number of the month having more demand than production : Number of the month having more production than demand

    Correct Option: B

    From the given bar diagram , we see
    Number of the month having more demand than production i.e.( January , March and May ) = 3
    Number of the month having more production than demand i.e. ( February , April ) = 2
    Required ratio = Number of the month having more demand than production : Number of the month having more production than demand
    ∴ Required ratio = 3 : 2


  1. What is the difference between average demand and average production of computers of the five months taken together?

    As per the given bar graph , we have
    Total demand of computers of the five months = 2500 + 100 + 2000 + 700 + 2800 = 8100
    Number of months = 5

    Average demand =
    8100
    = 1620
    5

    Total production of computers of the five months = 1000 + 1300 + 500 + 2200 + 1800 = 6800
    Number of months = 5
    Average production =
    6800
    = 1360
    5

    Correct Option: D

    As per the given bar graph , we have
    Total demand of computers of the five months = 2500 + 100 + 2000 + 700 + 2800 = 8100
    Number of months = 5

    Average demand =
    8100
    = 1620
    5

    Total production of computers of the five months = 1000 + 1300 + 500 + 2200 + 1800 = 6800
    Number of months = 5
    Average production =
    6800
    = 1360
    5

    Required difference = Average demand - Average production
    ∴ Required difference = 1620 – 1360 = 260


  1. The production of computers in April is approximately how many times that of production in January?

    From the given bar diagram , we see
    The production of computers in April = 2200
    The production of computers in January = 1000

    Required answer =
    The production of computers in April
    The production of computers in January

    Correct Option: A

    From the given bar diagram , we see
    The production of computers in April = 2200
    The production of computers in January = 1000

    Required answer =
    The production of computers in April
    The production of computers in January

    Required answer =
    2200
    = 2.2
    1000


  1. What percent of the demand of computers for the month of March is the demand of computers for the month of February?

    On the basis of given graph in question ,
    The demand of computers for the month of March = 2000
    The demand of computers for the month of February = 100

    Required percentage =
    The demand of computers for the month of February
    × 100
    The demand of computers for the month of March

    Correct Option: A

    On the basis of given graph in question ,
    The demand of computers for the month of March = 2000
    The demand of computers for the month of February = 100

    Required percentage =
    The demand of computers for the month of February
    × 100
    The demand of computers for the month of March

    Required percentage =
    100
    × 100 = 5%
    2000


  1. Which month has least demand of computers relative to production?

    According to given bar graph , we have

    January ⇒
    2500
    × 100 = 250%
    1000

    Febraury ⇒
    100
    × 100 =
    100
    %
    130013

    Correct Option: D

    According to given bar graph , we have

    January ⇒
    2500
    × 100 = 250%
    1000

    Febraury ⇒
    100
    × 100 =
    100
    %
    130013

    April ⇒
    700
    × 100 ≈ 32%
    2200

    Therefore , February month has least demand of computers relative to production .
