## Introduction to Data Interpretation

#### Data Interpretation

Direction: The pie– chart, given here shows monthly expenses on various heads and savings of the family of Mr. Rao. Study the chart and answer the questions based on it. 1. The amount spent on food exceeds the total amount spent on education and clothing by

1. According to given pie chart in question ,
Corresponding central angle :-
Food ⇒ 90°
Education + Clothing ⇒ 27 + 18 = 45°
Change in angle = 90° - 45° = 45°

 ∴ Required percent = Change in angle × 100 Corresponding central angle of ( Education + Clothing )

##### Correct Option: E

According to given pie chart in question ,
Corresponding central angle :-
Food ⇒ 90°
Education + Clothing ⇒ 27 + 18 = 45°
Change in angle = 90° - 45° = 45°

 ∴ Required percent = Change in angle × 100 Corresponding central angle of ( Education + Clothing )

 ∴ Required percent = 45° × 100 = 100% 45

Direction: The given pie-chart shows the spendings of a country on various sports during a year. Study the graph and answer the following questions. 1. What is the central angle for tennis?

1. As per the given pie chart in question ,
Percentage expenditure on tennis = 10%
As we know that , 100% ≡ 360°

 ∴ 1% = 360° 100

##### Correct Option: A

As per the given pie chart in question ,
Percentage expenditure on tennis = 10%
As we know that , 100% ≡ 360°

 ∴ 1% = 360° 100

 ∴ 10% ≡ 360 × 10 = 36° 100

1. The respective ratio of the total amount spent on football to that spent on hockey was

1. According to given pie chart in question ,
Percentage expenditure on hockey = 15%
Percentage expenditure on football = 15%
Required ratio = Percentage expenditure on hockey : Percentage expenditure on football

##### Correct Option: B

According to given pie chart in question ,
Percentage expenditure on hockey = 15%
Percentage expenditure on football = 15%
Required ratio = Percentage expenditure on hockey : Percentage expenditure on football
Required ratio = 15 : 15 = 1 : 1

1. If the total amount spent on sports during the year was \$ 12,000,000, how much was spent on basketball?

1. As per the given pie chart in question ,
Percentage expenditure on basketball = 12.5%
Total amount spent on sports during the year = \$ 12,000,000
∵ 100% ≡ \$ 12000000

 ∴ 1% = \$ 12000000 100

##### Correct Option: D

As per the given pie chart in question ,
Percentage expenditure on basketball = 12.5%
Total amount spent on sports during the year = \$ 12,000,000
∵ 100% ≡ \$ 12000000

 ∴ 1% = \$ 12000000 100

 ∴ 12.5% ≡ \$ 12000000 × 12.5 = \$ 1500000 100

1. If the total amount spent on sports during the year was \$ 15,000,000, the amount spent on cricket and hockey together was

1. According to given pie chart in question ,
Given , Total amount expenditure on sports = \$ 15,000,000
Percentage expenditure on cricket and hockey = ( 25 + 15 )% = 40%
∵ 100% ≡ \$ 15000000

 ∴ 1% = \$ 15000000 100

##### Correct Option: A

According to given pie chart in question ,
Given , Total amount expenditure on sports = \$ 15,000,000
Percentage expenditure on cricket and hockey = ( 25 + 15 )% = 40%
∵ 100% ≡ \$ 15000000

 ∴ 1% = \$ 15000000 100

 ∴ 40% ≡ \$ 15000000 × 40 = \$ 6000000 100
