    As per the given pie chart in question ,
    Total number of A, B, O and AB blood groups of donors = 150
    The corresponding angle of blood group ‘O’ donors = 100.8°
    The corresponding angle of all blood group donors = 360°

    Number of blood group ‘O’ donors =
    The corresponding angle of blood group ‘O’ donors
    		 × Total number of all blood groups of donors
    The corresponding angle of all blood group donors

    Correct Option: B

    As per the given pie chart in question ,
    Total number of A, B, O and AB blood groups of donors = 150
    The corresponding angle of blood group ‘O’ donors = 100.8°
    The corresponding angle of all blood group donors = 360°

    Number of blood group ‘O’ donors =
    The corresponding angle of blood group ‘O’ donors
    		 × Total number of all blood groups of donors
    The corresponding angle of all blood group donors

    Number of blood group ‘O’ donors =
    100.8
    		 × 150 = 42
    360

Direction: The pie- chart shows Distribution of Special Children Population during the year 1994-96. Study the pie-chart and answer the following questions.

    According to given pie chart in question ,
    Total number of children = 871 + 222 + 275 + 657 + 60 = 2085
    Number of children with language disorder = 657
    Number of children with disorders except language disorder = Total number of children : Number of children with language disorder
    Number of children with disorders except language disorder = 2085 – 657 = 1428

    Correct Option: A

    According to given pie chart in question ,
    Total number of children = 871 + 222 + 275 + 657 + 60 = 2085
    Number of children with language disorder = 657
    Number of children with disorders except language disorder = Total number of children : Number of children with language disorder
    Number of children with disorders except language disorder = 2085 – 657 = 1428

    Their average =
    1428
    		= 357
    4

    Required ratio = 657 : 357 = 219 : 119

  1. Find the ratio between articulatory disorder and speech disorder cases.








  1. View Hint View Answer Discuss in Forum

    On the basis of given pie chart in question ,
    Total number of children with articulatory disorder = 60
    and Total number of children with speech disorder = 275
    Required ratio = Total number of children with articulatory disorder : Total number of children with speech disorder

    Correct Option: D

    On the basis of given pie chart in question ,
    Total number of children with articulatory disorder = 60
    and Total number of children with speech disorder = 275
    Required ratio = Total number of children with articulatory disorder : Total number of children with speech disorder
    Required ratio = 60 : 275 = 12 : 55

  1. What is the average number of cases in different types of special children during the year 1994-96?

    As per the given pie chart in question ,
    Total number of children = 871 + 222 + 275 + 657 + 60 = 2085
    Total number types of special children = 5

    Required average =
    Total number of children
    Total number types of special children

    Correct Option: A

    As per the given pie chart in question ,
    Total number of children = 871 + 222 + 275 + 657 + 60 = 2085
    Total number types of special children = 5

    Required average =
    Total number of children
    Total number types of special children

    Required average =

  1. Find the approximate percentage distribution of children with auditory disorder.








  1. View Hint View Answer Discuss in Forum

    According to given pie chart in question ,
    Total number of children = 871 + 222 + 275 + 657 + 60 = 2085
    Number of children with auditory disorder = 871

    ∴ Required percent =
    Number of children with auditory disorder
    		 × 100 %
    Number of children with auditory disorder

    Correct Option: C

    According to given pie chart in question ,
    Total number of children = 871 + 222 + 275 + 657 + 60 = 2085
    Number of children with auditory disorder = 871

    ∴ Required percent =
    Number of children with auditory disorder
    		 × 100 %
    Number of children with auditory disorder

    ∴ Required percent =
    871
    		 × 100 ≈ 41.7%
