## Introduction to Data Interpretation

#### Data Interpretation

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

Direction: Study the following pie-chart and answer the questions.

1. The family actually spent \$ 4672 on grocery. Then the difference in the amount budgeted and spent on grocery is :

1. On the basis of given pie chart in question ,
Actually expenditure on grocery = \$ 4672
Expenditure percent on grocery = 20%
Total salary = \$ 32000 per month
Budgetary expenditure on grocery = 20% of \$ 32000

 Budgetary expenditure on grocery = \$ 32000 × 20 = \$ 6400 100

##### Correct Option: B

On the basis of given pie chart in question ,
Actually expenditure on grocery = \$ 4672
Expenditure percent on grocery = 20%
Total salary = \$ 32000 per month
Budgetary expenditure on grocery = 20% of \$ 32000

 Budgetary expenditure on grocery = \$ 32000 × 20 = \$ 6400 100

Required Difference = Budgetary expenditure on grocery - Actual expenditure on grocery
∴ Required Difference = \$ (6400 – 4672) = \$ 1728
