    On the basis of given bar diagram in question ,we see that one box represents the number of 20.
    Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000
    Number of accidents involving two-wheelers and two-wheelers = 230
    Number of accidents involving two-wheelers and other objects = 770

    Percentage of accidents involving two-wheelers and two wheelers =
    230
    		 × 100 = 23%
    1000

    Correct Option: D

    On the basis of given bar diagram in question ,we see that one box represents the number of 20.
    Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000
    Number of accidents involving two-wheelers and two-wheelers = 230
    Number of accidents involving two-wheelers and other objects = 770

    Percentage of accidents involving two-wheelers and two wheelers =
    230
    		 × 100 = 23%
    1000

    Percentage of accidents involving two-wheelers and other objects =
    770 × 100
    		= 77%
    1000

    ∴ Required difference = Percentage of accidents involving two-wheelers and other objects - Percentage of accidents involving two-wheelers and two wheelers
    Required difference = 77 – 23 = 54%

Direction: The following Pie Chart shows the export of different food grains from India in 2010. Study the chart and answer the questions :

  1. If the revenue from 1 quintal of crop A is thrice that from 1 quintal of crop C, then the ratio of the total revenues of A and C is

    As per the given above pie chart , we see
    The corresponding angle of crop A = 72°
    Total corresponding angle of crop C = 72°
    The revenue from crop A = 1 quintal
    The revenue from crop C = 1 quintal

    Correct Option: D

    As per the given above pie chart , we see
    The corresponding angle of crop A = 72°
    Total corresponding angle of crop C = 72°
    The revenue from crop A = 1 quintal
    The revenue from crop C = 1 quintal
    From question ,
    Required ratio = A : C = 3 × 72° : 1 × 36° = 6 : 1

  1. If a total of 1.5 million quintals of crop F was exported, then the total quantity of D and E that was exported (in million quintals) was

    On the basis of given pie chart in question ,
    The corresponding angle of crop F = 45°
    Total corresponding angle of food-grains = 360°
    The corresponding angle of crop D and E = ( 18 + 18 )° = 36°
    Total exported of crop F = 1.5 million quintals
    ∵ 45° = 1.5 million quintals

    Correct Option: A

    On the basis of given pie chart in question ,
    The corresponding angle of crop F = 45°
    Total corresponding angle of food-grains = 360°
    The corresponding angle of crop D and E = ( 18 + 18 )° = 36°
    Total exported of crop F = 1.5 million quintals
    ∵ 45° = 1.5 million quintals

    ∴ 36 ° =
    1.5 × 36
    		= 1.2 million quintals
    45

  1. The three crops which combine to contribute to exactly 50% of the total export of food grains are








  1. View Hint View Answer Discuss in Forum

    As per the given above question, we see in pie chart
    Total corresponding angle of food-grains = 360°
    The corresponding angle of crop ( A + B + C ) = 72° + 72° + 36° = 180° ,

    Correct Option: C

    As per the given above question, we see in pie chart
    Total corresponding angle of food-grains = 360°
    The corresponding angle of crop ( A + B + C ) = 72° + 72° + 36° = 180° ,
    Which represents the 50% of the total export of food grains in given pie chart .So , correct answer is option C .

  1. If a total of 1.5 million quintals of crop F was exported, the amount of total food grains exported (in million) quintals was

    On the basis of given pie chart in question ,
    Total export of crop F = 1.5 million quintals
    The corresponding angle of crop F = 45°
    Total corresponding angle of food-grains = 360°
    ∵ 45° = 1.5 million quintals

    Correct Option: B

    On the basis of given pie chart in question ,
    Total export of crop F = 1.5 million quintals
    The corresponding angle of crop F = 45°
    Total corresponding angle of food-grains = 360°
    ∵ 45° = 1.5 million quintals

    ∴ 360 ° =
    1.5 × 360
    		= 12 million quintals
    45
