On the basis of given pie chart in question ,
Corresponding angle for clothing = 36°
Corresponding angle for rent = 90°
Given that , Total expenditure = $ 8250Expenditure on clothes and rent = 8250 × (36° + 90°) 360°
Correct Option: A
On the basis of given pie chart in question ,
Corresponding angle for clothing = 36°
Corresponding angle for rent = 90°
Given that , Total expenditure = $ 8250Expenditure on clothes and rent = 8250 × (36° + 90°) 360° Expenditure on clothes and rent = 8250 × 126 = $ 2887.5 360 ∴ Average expenditure = 2887.5 = $ 1443.75 2

As per the given pie chart in question , we have
Corresponding angle for food = 108°
Corresponding angle for miscellaneous = 72°
Required ratio = Corresponding angle for food : Corresponding angle for miscellaneousCorrect Option: C
As per the given pie chart in question , we have
Corresponding angle for food = 108°
Corresponding angle for miscellaneous = 72°
Required ratio = Corresponding angle for food : Corresponding angle for miscellaneous
Required ratio = 108 : 72 = 3 : 2
 What percent of the total income does the family save?

As per the given pie chart in question ,
Corresponding angle for total expenditure = 360°
Percent of total expenditure = 100%
Corresponding angle for savings = 54°
∵ 360° ≡ 100%∴ Required percent = Percent of total expenditure × Corresponding angle for savings Corresponding angle for total expenditure
Correct Option: A
As per the given pie chart in question ,
Corresponding angle for total expenditure = 360°
Percent of total expenditure = 100%
Corresponding angle for savings = 54°
∵ 360° ≡ 100%∴ Required percent = Percent of total expenditure × Corresponding angle for savings Corresponding angle for total expenditure ∴ Required percent ≡ 100 × 54 = 15% 360
 What is the total monthly income of the family?

On the basis of given pie chart in question ,
Given that , Expenditure on clothes = Rs. 825.
The corresponding angle of total expenditure = 360°
The corresponding angle of expenditure on clothes = 36°
∵ 36° ≡ $ 825∴ Total monthly income = Expenditure on clothes × The corresponding angle of total expenditure The corresponding angle of expenditure on clothes
Correct Option: B
On the basis of given pie chart in question ,
Given that , Expenditure on clothes = Rs. 825.
The corresponding angle of total expenditure = 360°
The corresponding angle of expenditure on clothes = 36°
∵ 36° ≡ $ 825∴ Total monthly income = Expenditure on clothes × The corresponding angle of total expenditure The corresponding angle of expenditure on clothes ∴ Total monthly income = 825 × 360 = & 8250 36

On the basis of given pie chart in question , Corresponding angle for expense on food = 150°
Total expenditure amount = $ 7200
Corresponding angle for total expenditure = 360°
∵ 360° ≡ $ 7200∴ Expenditure on food = $ Total expenditure amount × Corresponding angle for expense on food Corresponding angle for total expenditure
Correct Option: D
On the basis of given pie chart in question , Corresponding angle for expense on food = 150°
Total expenditure amount = $ 7200
Corresponding angle for total expenditure = 360°
∵ 360° ≡ $ 7200∴ Expenditure on food = $ Total expenditure amount × Corresponding angle for expense on food Corresponding angle for total expenditure ∴ Expenditure on food = 150° ≡ $ 7200 × 150 = $ 3000 360
