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 ‘B’ donors = 129.6°
The corresponding angle of blood group ‘A’ donors = 72°
The corresponding angle of all blood group donors = 360°Persons with blood group A or B = (129.6 + 72) × 150 360
Correct Option: A

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

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 = 1428Correct 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 = 1428Their average = 1428 = 357 4
Required ratio = 657 : 357 = 219 : 119

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 disorderCorrect 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
